Abstract:
A system and method that reduces the descent velocity of an aerial vehicle, the system including a control system, an inflation device, and a deployable, inflatable cage. The control system detects a descent condition, such as an uncontrolled descent and activates the inflation device to inflate the cage to at least partially encase the aerial vehicle and protect the vehicle during descent and landing. The inflatable cage includes a main fill tube, a perimeter tube, and support tubes. The support tubes are connected between the main fill tube and the perimeter tube, and enable gas to flow from the inflation device through the support and perimeter tubes and into the perimeter tube. A drag inducing material enclosure is connected to the inflatable cage and structured to induce drag to reduce a descent speed of the aerial vehicle.

Description:
BACKGROUND 
       [0001]    Technical Field 
         [0002]    The present disclosure pertains to airborne object protection and, more particularly, to providing a system having a deployable assembly that attaches to the airborne object and when deployed provides parachute- and airbag-like properties to safely return the airborne object to the ground. 
         [0003]    Description of the Related Art 
         [0004]    Recent advancements in drone and personal-unmanned aerial vehicle technology have greatly reduced the cost of these vehicles and made them readily available to the general public. Although these vehicles are more affordable than in previous years, their cost is still significant enough to warrant some protection against damage resulting from an in-air failure. 
         [0005]    When an inflight failure occurs, aerial vehicles generally begin to plummet towards the ground. Inflight failures generally cannot be corrected before the vehicle hits the ground due to low flying altitudes or non-recoverable failures (e.g., a dead battery). Such crashes often leave the vehicle with major, or even irreparable, damage. 
         [0006]    Some aerial vehicles utilize traditional parachute systems to slow a descent of the vehicle. These parachute systems, however, generally work so long as the aerial vehicle is upright during the entire deployment phase of the parachute. Unfortunately, many failures result in sporadic and uncontrollable movement of the vehicle such that parachutes cannot be properly deployed, often resulting in the aerial vehicle crashing despite an attempt to deploy a traditional parachute system. It is with respect to these and other considerations that implementations of the present disclosure have been made. 
       BRIEF SUMMARY 
       [0007]    The present disclosure is directed to a system and method for resisting an uncontrolled descent of an aerial vehicle. 
         [0008]    In accordance with one aspect of the disclosure, the system includes an inflatable cage that is structured to be attached to and stored on the aerial vehicle and deployed from the aerial vehicle if the aerial vehicle enters an uncontrolled descent or loss of control state. The inflatable cage includes a hub, a plurality of support tubes, and a perimeter tube. Each of the support tubes is connected to the hub and the perimeter tube in a concave-like structure. One or more fill tubes are in fluid communication with the support tubes to enable inflation of the support tubes. An inflation mechanism is operable to inflate the inflatable cage in response to detection of an uncontrolled condition, such as an uncontrolled descent or loss of control of the aerial vehicle. 
         [0009]    In accordance with one aspect of the present disclosure, a second plurality of support tubes is connected to the perimeter tube opposite of the plurality of support tubes. These additional support tubes are structured to mobilize around the aerial vehicle while the inflatable cage is being deployed and to encase the aerial vehicle within the inflatable cage. 
         [0010]    The system also includes an enclosure that is connected to the inflatable cage. The enclosure may be parachute material that is structured to create drag to reduce a velocity or descent speed of the aerial vehicle when the inflatable cage and the enclosure are deployed together. The system also includes a plurality of weight distribution straps that are physically coupled between the aerial vehicle and the enclosure or the support tubes of the inflatable cage. In some implementations, the weight distribution straps are removably attached to a main fill tube such that the weight distribution straps separate from the main fill tube as the inflatable cage is deployed.

     DETAILED DESCRIPTION 
       [0034]    In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed implementations. However, one skilled in the relevant art will recognize that the present disclosed implementations may be practiced without one or more of these specific details or with other methods, components, materials, etc. In other instances, well-known structures or components or both that are associated with the environment of the present disclosure have not been shown or described in order to avoid unnecessarily obscuring descriptions of the implementations. 
         [0035]    Unless the context requires otherwise, throughout the specification and claims that follow, the word “comprise” and variations thereof, such as “comprises” and “comprising” are to be construed in an open inclusive sense, that is, as “including, but not limited to.” The foregoing applies equally to the words “including” and “having.” 
         [0036]    Reference throughout this description to “one implementation” or “an implementation” means that a particular feature, structure, or characteristic described in connection with the implementation is included in at least one implementation. Thus, the appearance of the phrases “in one implementation” or “in an implementation” in various places throughout the specification are not necessarily all referring to the same implementation. 
         [0037]    As used herein, the term “aerial vehicle” refers to a powered airborne object controlled by a user or autonomously, such as through an automated position-control system. Examples of aerial vehicles can include, but are not limited to, unmanned aerial vehicles, drones, manned aerial vehicles, or the like. 
         [0038]    Reference throughout this description to a “tube” means a lightweight, flexible, hollow body that can be inflated with a gas or other fluid to create a semi-rigid structure. Tubes can be linear, arcuate, circular, oval, or a variety of other shapes that perform similar functions to those that are described and illustrated herein. As described throughout, a tube may be a “fill tube,” a “support tube,” a “perimeter tube,” or other similar tubes. In general, fill tubes are connected to and in fluid communication with support tubes to provide fluid from an inflation mechanism to the support tubes and to the perimeter tube. In some implementations, fill tubes may connect to and be in fluid communication with the perimeter tube independent of the support tubes. As described herein, the support tubes (and the fill tubes in some implementations) in conjunction with the perimeter tube create a three-dimensional semi-solid structure of pressurized tube when deployed. The structure includes a concave-like portion such that when parachute material is attached to the concave-like portion and the system is deployed from an aerial vehicle, drag is created on the parachute material causing a velocity of the aerial vehicle to be reduced. 
         [0039]    Also referenced herein is a “hub,” which is a tubular unit where one or more tubes (e.g., fill tubes or support tubes) are connected to and in fluid communication with at least one input tube that distributes fluid from the input tube to the one or more tubes through the hub. It should be noted, however, that tubes can be connected to one another without a hub. 
         [0040]    The following is a brief description of the use, operation, and purpose of the inflatable parachute airbag system described herein. As the use of drones and other unmanned aerial vehicles increases, so too does the risk of inflight failures. Failures can occur in all different types of situations, environments, and vehicle altitudes. And the use of aerial vehicles in urban areas has increased the desire for a system to allow an aerial vehicle that experiences an inflight failure to land without causing harm to people, animals, homes, or other property. Similarly, aerial vehicle owners would like a system that protects the aerial vehicle from extensive damage due to a fall from altitude. 
         [0041]    The system includes a detection computer system, sensors, an inflation mechanism or device, and an inflatable parachute airbag assembly. The detection computer system, or control circuitry, is operable to detect an uncontrolled flight condition of the aerial vehicle and to output a signal in response to the detected condition. These detection systems utilize different types of sensors, such as gyroscopes, accelerometers, altimeters, GPS systems, or the like, and algorithms to detect if the aerial vehicle has gone into an uncontrolled condition. An uncontrolled condition may be an uncontrolled descent, an unintentional unpowered descent, other uncontrolled movements, flight of the aerial vehicle into an unapproved or unauthorized location or altitude, etc. 
         [0042]    Examples of an uncontrolled flight condition may be that the motor(s) of the aerial vehicle lose power—resulting in a loss of lift to the aerial vehicle. Another uncontrolled flight condition may be that the aerial vehicle stops responding to operating commands from a remote control of a user. In yet another example, the aerial vehicle may be too close to the ground or near structures or is on a collision course with a structure or person. It should be recognized that other uncontrolled or potentially hazardous flight conditions also may be detected by the detection computer system. 
         [0043]    Upon detection of an uncontrolled flight condition, the detection computer system outputs a signal that can be used for a variety of different safety measures. For example, the signal can bypass the avionics controller and cut power to the motors, which stops the motors and the attached rotors from spinning. The signal is also received by a controller of the inflation mechanism and is configured to initiate deployment of an inflatable parachute airbag assembly, as described herein. In some implementations, users can manually input, such as from a remote control, the detection signal to initiate deployment of the inflatable parachute airbag assembly. 
         [0044]    Upon receiving the fall detection signal, a servo or other controller opens or otherwise activates the inflation mechanism—which is in fluid communication with the inflatable parachute airbag assembly—to inflate, and thus deploy, the inflatable parachute airbag assembly. As described elsewhere, the inflation mechanism may be compressed air, a pump, a solid-propellant inflator, other explosion- or chemical-based inflators, etc. 
         [0045]    Prior to deployment, the inflatable parachute airbag assembly is stored in a deflated state in a housing on the aerial vehicle. As described herein, the inflatable parachute airbag assembly includes a plurality of different tubes (e.g., fill tubes, support tubes, perimeter tube, etc.). These tubes may be made of any of a variety of different lightweight materials that are capable of holding air pressure when the inflatable parachute airbag assembly is deployed. Additionally, the tubes are flexible and, when deflated, collapse into a compact form for storage on the aerial vehicle. The inflatable parachute airbag assembly maintains this compact form until inflated. 
         [0046]    Upon deployment, an initial burst of gas from the inflation mechanism pushes the inflatable parachute airbag assembly out of its housing and away from aerial vehicle. This burst of gas likewise pushes the aerial vehicle in an opposite direction of the deployment of the inflatable parachute airbag assembly, which helps to create some distance between the aerial vehicle and the inflatable parachute airbag assembly. This partial separation allows the inflatable parachute airbag assembly to proper inflate, pressurize, and fully deploy without interference by the aerial vehicle. 
         [0047]    As the tubes of the inflatable parachute airbag assembly are inflated and become pressurized, the entire inflatable parachute airbag assembly expands to a shape pre-defined by its structure. In some implementations, the inflatable parachute airbag assembly expands around the aerial vehicle in a mouth-like motion to fully encase the aerial vehicle in a spherical-like shape. In other implementations, the inflatable parachute airbag assembly does not fully encase the aerial vehicle, but is rather a concave-like structure that is operative as a semi-solid parachute. 
         [0048]    In various implementations, the inflatable parachute airbag assembly is a closed assembly so that once inflated and pressurized it remains in that semi-solid state for a suitable amount of time to allow the aerial vehicle to descend and come to rest on the ground. 
         [0049]      FIGS. 1A-1D  are various views depicting utilization of an inflatable parachute airbag system  112  in accordance with the present disclosure. Many aerial vehicles include one or more mounting brackets for various different types of equipment, such as cameras, payload supports, etc.  FIG. 1A  shows an aerial vehicle  102  with a mounting bracket  104 . In this illustration, the mounting bracket  104  is positioned to the back of the aerial vehicle  102 . Attached to the mounting bracket is the inflatable parachute airbag assembly  112 . Although the inflatable parachute airbag assembly  112  is positioned in the back of the aerial vehicle  102  for purposes of discussion, it could be attached to other positions of the aerial vehicle, such as on top, in front, on bottom, etc. Additionally, other components (not shown) of the inflatable parachute airbag system may be attached to or embedded in the aerial vehicle. For example, the aerial vehicle may include an on-board detection system and sensors to detect an uncontrolled flight condition. In other implementations, the detection system or the sensors, or both, may be separate from and attached to the aerial vehicle along with the inflatable parachute airbag assembly. 
         [0050]    The inflatable parachute airbag assembly  112  is stored in a housing  108  and attached to the bracket  104 . The housing  108  is also in fluid communication with an inflation mechanism  106 . The inflation mechanism  106  may be compressed air, a pump, a solid-propellant inflator, other explosion- or chemical-based inflators, etc. Upon deployment of the inflatable parachute airbag assembly  112  from the aerial vehicle  102 , the inflation mechanism  106  provides gas to the inflatable parachute airbag assembly  112 , which inflates and pressurizes the inflatable parachute airbag system  112 . It should be recognized that various implementations of the inflatable parachute airbag systems described herein can be similarly attached to and deployed from an aerial vehicle. 
         [0051]      FIGS. 1B-1D  provide a basic illustration of the deployment of one implementation of the inflatable parachute airbag assembly  112 . As gas is transferred from the inflation mechanism  106 , it enters a main fill tube  110 , which, as described above, pushes the inflatable parachute airbag assembly  112  out of the housing  108  and away from the aerial vehicle. Gas from the inflation tube  110  enters a top hub  118 , which distributes the gas into a plurality of support tubes  115 , a perimeter tube  113 , and two bottom support tubes  114  and  116 . The bottom support tubes  114  and  116  guide the inflatable parachute airbag assembly  112  around the aerial vehicle in a mouth-like fashion as they inflate. 
         [0052]    Parachute material (not illustrated) is connected to the inflatable parachute airbag assembly  112  around (or inside) the plurality of support tubes  115  between the perimeter tube  116  and the top hub  118  to create a concave-like structure that is operative as a parachute. In some implementations, mesh material (not illustrated) may be connected between the perimeter tube  113  and the bottom support tubes  114  and  116  to provide additional protection to the aerial vehicle while still allowing air to flow into the parachute material. It should be noted that the mesh material is not connected between the bottom support tubes  114  and  116  so as not to interfere with their function of allowing the inflatable parachute airbag assembly to inflate around the aerial vehicle. 
         [0053]    Top and bottom views of the deployed inflatable parachute airbag assembly  112  are illustrated in  FIGS. 2A and 2B . As can be seen from these figures, the top hub  118  connects to and is in fluid communication with a plurality of support tubes  115 . The plurality of support tubes  115  are also connected to a perimeter tube  113 . Also connected to the perimeter tube  113  are the bottom support tubes  114  and  116 . The perimeter tube  113  provides transverse support to extend the inflatable parachute airbag assembly away from the aerial vehicle as the bottom support tubes  114  and  116  inflate and the inflatable parachute airbag assembly encases the aerial vehicle. 
         [0054]    The remaining illustrations show various implementations of the inflatable parachute airbag assembly in a fully deployed and pressurized state. For ease of illustration, some of the figures do not include the parachute material, or the mesh material, depending on the implementation. Additionally, other components of the inflatable parachute airbag system (e.g., the uncontrolled-flight-condition detection system, sensors, and inflation mechanism) may not be shown or described in order to avoid unnecessarily obscuring descriptions of the implementations of the inflatable airbag assembly. 
         [0055]      FIGS. 3A-3C  are bottom left perspective views of inflatable parachute airbag assemblies  100 A- 100 C, respectively. The inflatable parachute airbag assembly  100 A, as illustrated in  FIG. 3A , includes a plurality of top support tubes  120   a - 120   h,  a main fill tube  122 , a plurality of fill tubes  124   a - 124   h,  a plurality of bottom support tubes  123 ,  125 , and  126   a - 126   f,  and a perimeter tube  121 . The inflatable parachute airbag assembly  110 A also includes a bottom hub  119  and a top hub  117 . 
         [0056]    The bottom hub  119  is operative to distribute gas from an inflation mechanism (not illustrated) into the main fill tube  122  and the plurality of fill tubes  124   a - 124   h.  In some implementations, the bottom hub  119  provides a connection point for the inflatable parachute airbag assembly  100 A to connect to an aerial vehicle. 
         [0057]    The main fill tube  122  is connected to and in fluid communication between the bottom hub  119  and the top hub  117 . The main fill tube  122  is operative as an input tube to the top hub  117  such that gas passes from the bottom hub  119  to the top hub  117 . 
         [0058]    The plurality of top support tubes  120   a - 120   h  are connected to and in fluid communication with the top hub  117 . The top hub  117  is operative to distribute gas from the main fill tube  122  into the plurality of top support tubes  120   a - 120   h.  In some implementations, some support tubes of the plurality of top support tubes  120   a - 120   h  may be connected to the top hub  117  but not in fluid communication with the top hub  117 . In such an implementation, those support tubes may be inflated through respective fill tubes of the plurality of fill tubes  124   a - 124   h,  as described below, but not through the top hub  117 . 
         [0059]    The top hub  117  acts as a central location for the plurality of top support tubes  120   a - 120   h  to be connected. It should be noted that the top hub  117  may be a variety of different shapes or structures. For example, the top hub  117  may be a ring or annulus, a square, a triangle, a pentagon, an octagon, or other shape that is operative to connect to and inflate the top support tubes  120   a - 120   h.    
         [0060]    The plurality of top support tubes  120   a - 120   h  are also connected to and in fluid communication with the perimeter tube  121 . The plurality of top support tubes  120   a - 120   h  are operative to inflate the perimeter tube  121 . In some implementations, some support tubes of the plurality of top support tubes  120   a - 120   h  may be connected to the perimeter tube  121  but not in fluid communication with the perimeter tube  121 . In such an implementation, the perimeter tube  121  may be inflated through those support tubes that are in fluid communication with the perimeter tube  121  or through a separate fill tube (not illustrated) connected to and in fluid communication with the main fill tube  122  or the bottom hub  119 . 
         [0061]    Each of the top support tubes  120   a - 120   h  is positioned between the top hub  117  and the perimeter tube  121 . The top support tubes  120   a - 120   h  may be symmetrically positioned radially around a central axis of the perimeter tube  121 . In some implementations, a distance between each of the top support tubes  120   a - 120   h  may be substantially similar, but other configurations of top support tubes may be utilized. Similarly, although the inflatable parachute airbag assembly  100 A is illustrated with eight top support tubes, more or less top support tubes may be utilized such that the top support tubes create a concave-like structure that, when covered by a parachute material, can create drag when the inflatable parachute airbag  100 A is deployed from an inflight aerial vehicle. 
         [0062]    It should be noted that the concave-like structure created by the top support tubes  120   a - 120   h  and the perimeter tube  121  can take on various different three-dimensional shapes. Briefly, for example, the perimeter tube  121  could be an oval, square, annulus, triangle, pentagon, octagon, or other shape, while the top support tubes  120   a - 120   h  may be straight, arcuate, or the like and may include a variety of different numbers of support tubes that are positioned radially around a central axis of the perimeter tube  121  such that the resulting concave-like structure may be domelike, conical, pyramidal hexagonal, cubical, frustum-like, etc. 
         [0063]    As mentioned above, the plurality of top support tubes  120   a - 120   h  are inflated through the top hub  117 . The plurality of top support tubes  120   a - 120   h  are also inflated via the plurality of fill tubes  124   a - 124   h.  The plurality of fill tubes  124   a - 124   h  are connected to and in fluid communication with the bottom hub  119 . Each of the plurality of fill tubes  124   a - 124   h  is also connected to and in fluid communication with a respective support tube of the plurality of top support tubes  120   a - 120   h.  The plurality of fill tubes  124   a - 124   h  are operative to inflate the plurality of top support tubes  120   a - 120   h.    
         [0064]    In various implementations, the fill tubes  124   a - 124   h  may connect to a body portion of the top support tubes  120   a - 120   h  between the top hub  117  and the perimeter tube  121 . For example, the fill tube  124   c  connects to the bottom hub  119  and the body of the top support tube  120   c  and is operative to provide gas from the bottom hub  119  to the top support tube  120   c.  As illustrated, the bottom hub  119  is positioned below (or closer to the perimeter tube  121  than) the connection points of the fill tubes  124   a - 124   h  to the top support tubes  120   a - 120   h.  However, implementations are not so limited, and other positions of the bottom hub  119  relative to the perimeter tube  121  (e.g., a length of the main fill tube  122 ) or other positions of the connection points of the fill tubes  124   a - 124   h  to the top support tubes  120   a - 120   h  may be utilized. 
         [0065]    The inflatable parachute airbag assembly  100 A also includes a plurality of bottom support tubes  123 ,  125 , and  126   a - 126   f.  The ends of each of the bottom support tubes  123  and  125  connect to and are in fluid communication with the perimeter tube  121 . The ends of each of the bottom support tubes  123  and  125  are substantially, diametrically opposed relative to a central axis of the perimeter tube  121 . In some implementations, the ends of the bottom support tube  123  may merge with respective ends of the bottom support tube  125  such that single merged tubes connect to the perimeter tube  121 . 
         [0066]    The bottom support tubes  126   a - 126   f  are connected to and in fluid communication with the perimeter tube  121 . The bottom support tubes  126   a - 126   f  extend downwards and away from the perimeter tube  121  towards a central axis of the perimeter tube  121 . Unlike the top support tubes  120   a - 120   h  that connect to the top hub  117 , the bottom support tubes  126   a - 126   f  do not connect to one another or to another hub. But implementations are not so limited. For example, the bottom support tubes  126   a - 126   c  may be connected to the bottom support tube  125  and the bottom support tubes  126   d - 126   f  may be connected to the bottom support tube  126 , similar to what is illustrated in  FIGS. 1B-1D  or described below in conjunction with  FIGS. 17A-17E . In such an implementation, the bottom support tubes  126   a - 126   f  may or may not be in fluid communication with the bottom support tubes  123  or  125 , since the bottom support tubes  123  and  125  are inflated from the perimeter tube  121 . 
         [0067]    As illustrated, the top support tubes  120   a - 120   h  and bottom support tubes  126   a - 126   f,    123 , and  125  are separate tubes that connect to the perimeter tube  121  substantially, diametrically opposite of each other. Implementations, however, are not so limited. For example, the inflatable parachute airbag assembly  100 A may include a plurality of support tubes (not illustrated) that each includes a respective top support tube of the top support tubes  120   a - 120   f  and a respective bottom support tube of the bottom support tubes  126   a - 126   f  with a single fluid communication connection with the perimeter tube  121 . Such support tubes may be positioned within or outside the central aperture of the perimeter tube  121 . It should be noted that various different numbers and configurations of support tubes (e.g., top and bottom support tubes) and perimeter tubes may be employed. 
         [0068]    When deployed, the inflation mechanism provides gas to the bottom hub  119 , which distributes the gas to the main fill tube  122  and the plurality of fill tubes  124   a - 124   h.  By first distributing the gas to the main fill tube  122  and the plurality of fill tubes  124   a - 124   h,  the inflatable parachute airbag assembly  100 A is pushed in a direction of the top hub  117 , which pushes the inflatable parachute airbag assembly  100 A and the aerial vehicle away from each other—creating an initial separation between the aerial vehicle and the top hub  117 . The main fill tube  122  and the plurality of fill tubes  124   a - 124   h  then inflate the top support tubes  120   a - 120   h,  the perimeter tube  121 , the bottom support tubes  123  and  125 , and the bottom support tubes  126   a - 126   f.  The initial separation of the aerial vehicle and the top hub  117  allows for the support tubes and the perimeter tube to fully inflate such that the inflatable parachute airbag assembly  100 A deploys around the aerial vehicle without interference by the aerial vehicle. 
         [0069]      FIG. 3B  illustrates an inflatable parachute airbag assembly  100 B, which is an implementation of the inflatable parachute airbag assembly  100 A shown in  FIG. 3A . But the inflatable parachute airbag assembly  100 B includes a parachute material  129  on a top portion  127  of the inflatable parachute airbag assembly  100 B. The parachute material  129  can be positioned and connected to an outside, as illustrated, or an inside of the top support tubes relative to the main fill tube such that air pushes against the parachute material when deployed. The parachute material can be any of a variety of lightweight materials that can be used to create drag. 
         [0070]    Upon deployment of the inflatable parachute airbag assembly  100 B, air flows through the spaces between the bottom support tubes of the bottom portion  128  (because there is no parachute material  129  on the bottom portion  128 ) and into the concave-like structure of the top portion  127 , which creates drag on the parachute material  129 . This drag slows the descent of the aerial vehicle, which can reduce damage to objects or people on the ground, as well as to the aerial vehicle itself. 
         [0071]      FIG. 3C  illustrates an inflatable parachute airbag assembly  100 C, which is an implementation of the inflatable parachute airbag assembly  100 B shown in  FIG. 3B . But the inflatable parachute airbag assembly  100 C also includes a mesh material  130  on the bottom portion  128  of the inflatable parachute airbag assembly  100 C. The mesh material  130  can be positioned and connected to an outside or an inside of the support tubes relative to the main fill tube such that air pushes against the parachute material when deployed. The mesh material can be any of a variety of lightweight materials that are air permeable. 
         [0072]    Upon deployment of the inflatable parachute airbag assembly  100 C, air flows through the mesh material  130  and into the concave-like structure of the top portion  127 , which creates drag on the parachute material  129 . The mesh material  130  also provides additional protection to the aerial vehicle encased in the inflatable parachute airbag assembly  100 C so that tree branches and other debris do not impact the aerial vehicle as it descends to the ground. Similarly, the mesh material  130  adds additional protection so that if the rotors are still turning, they do not pose an additional hazard to people or objects on the ground. 
         [0073]      FIGS. 4-7  illustrate various other views of the inflatable parachute airbag assembly  100 A shown in  FIG. 3A . As illustrated, the top support tubes  120   a - 120   h  are connect at one end to the top hub  117  and at the other end to the perimeter tube  121 . The fill tubes  124   a,    124   b,    124   c,    124   d,    124   e,    124   f,    124   g,  and  124   h  connect to the top support tubes  120   a,    120   b,    120   c,    120   d,    120   e,    120   f,    120   g,  and  120   h,  respectively, and enable gas to flow into and inflate the respective support tubes. 
         [0074]    The bottom support tubes  126   a - 126   f  connect at one end to the perimeter tube  121  and the other end is sealed and terminates near the bottom support tubes  123  and  125 . But, as described above, in some implementations, the bottom support tubes  126   a - 126   c  and  126   d - 126   f  connect to the bottom support tubes  125  and  123 , respectively. As described above, the ends of the bottom support tubes  125  and  123  connect to the perimeter tube  121  such that their ends are substantially, diametrically opposed relative to a central axis of the perimeter tube  121 , which creates a void longitudinally between the bottom support tubes  125  and  123 . 
         [0075]    As the inflatable parachute airbag assembly  100 A inflates upon deployment, the bottom support tubes  125  and  123  inflate in opposite directions of each other (e.g., increasing the void between them during the inflation process), enabling the inflatable parachute airbag assembly  100 A to inflate and envelop the aerial vehicle in a mouth-like fashion before coming back together (e.g., decreasing the void between them once substantially inflated). Once fully inflated, the bottom support tubes  125  and  123  are positioned adjacent to one another. In some implementations, the bottom support tubes  125  and  123  may include additional removable connectors to attach to one another, such as hook and loop connectors, motorized clasp locker or slide fastener, etc. 
         [0076]    It should be noted that a back view of the inflatable parachute airbag assembly  100 A would substantially mirror the front view illustrated in  FIG. 4 . Similarly, a left view of the inflatable parachute airbag assembly  100 A would substantially mirror the right view illustrated in  FIG. 5 . 
         [0077]      FIG. 8A  is a front cross-section view of the inflatable parachute airbag assembly  100 A, as described above. Many of the details of the inflatable parachute airbag assembly  100 A are not reiterated here, but briefly, a housing  131  stores the inflatable parachute airbag assembly  100 A in an uninflated state, and may contain an inflation mechanism (not illustrated). The housing  131  may be a variation of the housing  108  in  FIG. 1A  and physically coupled to an aerial vehicle  134 . 
         [0078]    As described herein, when a fall of the aerial vehicle  134  is detected, the inflatable parachute airbag assembly  100 A is deployed and inflated. The main fill tube  122  and the fill tubes  124   a,    124   b,    124   e,  and  124   h  are inflated via the bottom hub  119 , which is in fluid communication with the inflation mechanism. The top support tubes  120   a,    120   b,    120   e,  and  120   f  connect between the top hub  117  and the perimeter tube  121 . The top support tubes  120   a,    120   b,    120   e,  and  120   f  are inflated via the fill tubes  124   a,    124   b,    124   e,  and  124   f,  respectively, and via the top hub  117 . The bottom support tubes  126   a,    126   b,    126   e,  and  126   f  are connected to the perimeter tube  121  and extend downwards and away from the perimeter tube towards a central axis of the perimeter tube  121 . And each of the bottom support tubes  123  and  125  connect to the perimeter tube  121  in an arcuate structure to provide a mouth-like aperture to enable the inflatable parachute airbag assembly  100 A to inflate around the aerial vehicle  134 . 
         [0079]    The inflatable parachute airbag assembly  100 A also includes a plurality of support straps  132   a - 132   b  coupled between the aerial vehicle  134  and the inflatable parachute airbag assembly  100 A. The support straps  132   a - 132   b  may be selected from variety of different suitable lightweight materials that are strong enough to resist breaking while keeping the inflatable parachute airbag assembly  100 A attached to the aerial vehicle  134  as the aerial vehicle  134  and the deployed inflatable parachute airbag assembly  100 A descend to the ground. Although the cross-section view only shows two support straps, a plurality of support straps are distributed substantially evenly and radially around the center axis of the perimeter tube  121  to provide stabilization and support for the deployed inflatable parachute airbag assembly  100 A and the aerial vehicle  134 . 
         [0080]    In various implementations, one end of the support straps  132   a - 132   b  connects to the housing  131 , which is connected to the aerial vehicle  134 . In other implementations, the support straps  132   a - 132   b  may be directly connected to the aerial vehicle  134  rather than to the housing  131 . The other end of the support straps  132   a - 132   b  connects to the parachute material (not illustrated), which is illustrated in  FIGS. 8B-8C . In other implementations, the support straps  132   a - 132   b  may be connected to some of the top support tubes  120   a,    120   b,    120   e,  and  120   f  such that the support straps are distributed substantially evenly and radially around the center axis of the perimeter tube  121 . 
         [0081]      FIG. 8B  is a front cross-section view of the inflatable parachute airbag assembly  100 B, as described above. As illustrated, the support straps  132   a - 132   b  connect to the parachute material  129  in the top portion  127  of the inflatable parachute airbag assembly  100 B, while the bottom portion  128  is open to allow air to flow into the inflatable parachute airbag assembly  100 B and create drag on the parachute material  129 , as described above in conjunction with  FIG. 3B . It should be noted that no parachute material is positioned planar to and inside the central opening of the perimeter tube  121 . 
         [0082]      FIG. 8C  is a front cross-section view of the inflatable parachute airbag assembly  100 C, as described above. Similar to what is illustrated in  FIG. 8B , the support straps  132   a - 132   b  connect to the parachute material  129  in the top portion  127  of the inflatable parachute airbag assembly  100 B. In some implementations, the mesh material  130  may cover the bottom portion  128  to provide additional protection of the aerial vehicle while still allowing air to flow into the inflatable parachute airbag assembly  100 B and create drag on the parachute material  129 , as described above in conjunction with  FIG. 3C . As noted in the illustration, there is no mesh material  130  between the bottom support tubes  123  and  125 . 
         [0083]      FIG. 9  is a bottom left perspective view of an alternative inflatable parachute airbag assembly  200 . The inflatable parachute airbag assembly  200  includes a plurality of support tubes  140   a - 140   h,  a main fill tube  146 , a plurality of fill tubes  142   a - 142   h,  and a perimeter tube  139 . The inflatable parachute airbag assembly  200  also includes a bottom hub  147  and a top hub  145 . The plurality of support tubes  140   a - 140   h,  the main fill tube  146 , the plurality of fill tubes  142   a - 142   h,  the perimeter tube  139 , the bottom hub  147 , and the top hub  145  are variations of the plurality of top support tubes  120   a - 120   h,  the main fill tube  122 , the plurality of fill tubes  124   a - 124   h,  the perimeter tube  121 , the bottom hub  119 , and the top hub  117  illustrated in  FIG. 3A . 
         [0084]    The bottom hub  147  is operative to distribute gas from an inflation mechanism (not illustrated) into the main fill tube  146  and the plurality of fill tubes  142   a - 142   h.  In some implementations, the bottom hub  147  provides a connection point for the inflatable parachute airbag assembly  200  to connect to an aerial vehicle. 
         [0085]    The main fill tube  146  is connected to and in fluid communication between the bottom hub  147  and the top hub  145 . The main fill tube  146  is operative as an input tube to the top hub  145  such that gas passes from the bottom hub  147  to the top hub  145 . 
         [0086]    The plurality of support tubes  140   a - 140   h  are connected to and in fluid communication with the top hub  145 . The top hub  145  is operative to distribute gas from the main fill tube  146  into the plurality of support tubes  140   a - 140   h.  In some implementations, some support tubes of the plurality of support tubes  140   a - 140   h  may be connected to the top hub  145  but not in fluid communication with the top hub  145 . In such an implementation, those support tubes may be inflated through respective fill tubes of the plurality of fill tubes  142   a - 142   h,  as described below, but not through the top hub  145 . 
         [0087]    The top hub  145  acts as a central location for the plurality of support tubes  140   a - 140   h  to be connected. It should be noted that the top hub  145  may be a variety of different shapes or structures. For example, the top hub  145  may be a ring or annulus, a square, a triangle, a pentagon, an octagon, or other shape that is operative to connect to and inflate the support tubes  140   a - 140   h.    
         [0088]    The plurality of support tubes  140   a - 140   h  are also connected to and in fluid communication with the perimeter tube  139 . The plurality of support tubes  140   a - 140   h  are operative to inflate the perimeter tube  139 . In some implementations, some support tubes of the plurality of support tubes  140   a - 140   h  may be connected to the perimeter tube  139  but not in fluid communication with the perimeter tube  139 . In such an implementation, the perimeter tube  139  may be inflated through those support tubes that are in fluid communication with the perimeter tube  139  or through a separate fill tube (not illustrated) connected to and in fluid communication with the main fill tube  146  or the bottom hub  147 . 
         [0089]    Each of the support tubes  140   a - 140   h  is positioned between the top hub  145  and the perimeter tube  139 . The support tubes  140   a - 140   h  may be symmetrically positioned radially around a central axis of the perimeter tube  139 . In some implementations, a distance between each of the support tubes  140   a - 140   h  may be substantially similar, but other configurations of support tubes may be utilized. Similarly, although the inflatable parachute airbag assembly  200  is illustrated with eight support tubes, more or less support tubes may be utilized such that the support tubes create a concave-like structure that, when covered by a parachute material, can create drag when the inflatable parachute airbag assembly  200  is deployed from an aerial vehicle. 
         [0090]    It should be noted that the concave-like structure created by the support tubes  140   a - 140   h  and the perimeter tube  139  can take on various different three-dimensional shapes. Briefly, for example, the perimeter tube  139  could be an oval, square, annulus, triangle, pentagon, octagon, or other shape, while the support tubes  140   a - 140   h  may be straight, arcuate, or the like and may include a variety of different numbers of support tubes that are positioned radially around a central axis of the perimeter tube  139  such that the resulting concave-like structure may be domelike, conical, pyramidal hexagonal, cubical, frustum-like, etc. 
         [0091]    As mentioned above, the plurality of support tubes  140   a - 140   h  are inflated through the top hub  145 . The plurality of support tubes  140   a - 140   h  are also inflated via the plurality of fill tubes  142   a - 142   h.  The plurality of fill tubes  142   a - 142   h  are connected to and in fluid communication with the bottom hub  147 . Each of the plurality of fill tubes  142   a - 142   h  is also connected to and in fluid communication with a respective support tube of the plurality of support tubes  140   a - 140   h.  The plurality of fill tubes  142   a - 142   h  are operative to inflate the plurality of support tubes  140   a - 140   h.    
         [0092]    In various implementations, the fill tubes  142   a - 142   h  may connect to a body portion of the support tubes  140   a - 140   h  between the top hub  145  and the perimeter tube  139 . For example, the fill tube  142   a  connects to the bottom hub  147  and the body of the support tube  140   a  and is operative to provide gas from the bottom hub  147  to the support tube  140   a.  As illustrated, the bottom hub  147  is positioned below (or closer to the perimeter tube  139  than) the connection points of the fill tubes  142   a - 142   h  to the support tubes  140   a - 140   h.  However, implementations are not so limited, and other positions of the bottom hub  147  relative to the perimeter tube  139  (e.g., a length of the main fill tube  146 ) or other positions of the connection points of the fill tubes  142   a - 142   h  to the support tubes  140   a - 140   h  may be utilized. 
         [0093]    When deployed, the inflation mechanism provides gas to the bottom hub  147 , which distributes the gas to the main fill tube  146  and the plurality of fill tubes  142   a - 142   h.  By first distributing the gas to the main fill tube  146  and the plurality of fill tubes  142   a - 142   h,  the inflatable parachute airbag assembly  200  is pushed in a direction of the top hub  145 , which pushes the inflatable parachute airbag assembly  200  and the aerial vehicle away from each other—creating an initial separation between the aerial vehicle and the top hub  145 . The main fill tube  146  and the plurality of fill tubes  142   a - 142   h  then inflate the support tubes  140   a - 140   h  and the perimeter tube  139 , respectively. The initial separation of the aerial vehicle and the top hub  145  allows for the support tubes  140   a - 140   h  and the perimeter tube  139  to fully inflate such that the inflatable parachute airbag assembly  200  deploys without interference by the aerial vehicle. 
         [0094]    Although not illustrated in  FIG. 9 , for clarity of the figure, the inflatable parachute airbag assembly  200  also includes a parachute material. The parachute material would be similar to the parachute material  129  on the top portion  127  of the inflatable parachute airbag assembly  100 B in  FIG. 3B . The parachute material can be positioned and connect to the support tubes on the outside or inside of the support tubes relative to the main fill tube such that air pushes against the parachute material when deployed. It should be noted that no parachute material is positioned planar to and inside the central opening of the perimeter tube  139 . The parachute material can be any of a variety of lightweight materials that can be used to create drag. 
         [0095]    Upon deployment of the inflatable parachute airbag assembly  200 , air flows through a central opening of the perimeter tube  139  and into the concave-like structure created by the support tubes  140   a - 140   h,  which creates drag on the parachute material. This drag slows the descent of the aerial vehicle, which can reduce damage to objects or people on the ground, as well as to the aerial vehicle itself. 
         [0096]      FIGS. 10-13  illustrate various other views of the inflatable parachute airbag assembly  200  shown in  FIG. 9 . As illustrated, the support tubes  140   a - 140   h  are connected at one end to the top hub  145  and at the other end to the perimeter tube  139 . The fill tubes  142   a,    142   b,    142   c,    142   d,    142   e,    142   f,    142   g,  and  1424   h  connect to the top support tubes  140   a,    140   b,    140   c,    140   d,    140   e,    140   f,    140   g,  and  140   h,  respectively, and enable gas to flow into and inflate the respective support tubes. 
         [0097]    It should be noted that a back view of the inflatable parachute airbag assembly  200  would substantially mirror the front view illustrated in  FIG. 10 . Similarly, a left view of the inflatable parachute airbag assembly  200  would substantially mirror the right view illustrated in  FIG. 11 . 
         [0098]      FIGS. 14A and 14B  are front cross-section views of the inflatable parachute airbag assembly  200 , as described above. Many of the details of the inflatable parachute airbag assembly  200  are not reiterated here, but briefly, a housing  143  is included in the system that is configured to store the inflatable parachute airbag assembly  200  in an uninflated state, and may contain an inflation mechanism (not illustrated). The housing  143  may be a variation of the housing  131  in  FIG. 8A  and physically coupled to an aerial vehicle  151 . 
         [0099]    As described herein, when a fall of the aerial vehicle  151  is detected, the inflatable parachute airbag assembly  200  is deployed and inflated. The main fill tube  146  and the fill tubes  142   c,    142   d,    142   f,  and  142   g  are inflated via the bottom hub  147 , which is in fluid communication with the inflation mechanism. The support tubes  140   c,    140   d,    140   f,  and  140   g  connect between the top hub  145  and the perimeter tube  139 . The support tubes  140   c,    140   d,    140   f,  and  140   g  are inflated via the fill tubes  142   c,    142   d,    142   f,  and  142   g,  respectively, and via the top hub  145 . 
         [0100]    The inflatable parachute airbag assembly  200  also includes a plurality of support straps  144   a - 144   b  coupled between the aerial vehicle  151  and the inflatable parachute airbag assembly  200 . The support straps  144   a - 144   b  may be selected from variety of different suitable lightweight materials that are strong enough to resist breaking while keeping the inflatable parachute airbag assembly  200  attached to the aerial vehicle  151  as the aerial vehicle  151  and the deployed inflatable parachute airbag assembly  200  descend to the ground. Although the cross-section view only shows two support straps, a plurality of support straps are distributed substantially evenly and radially around the center axis of the perimeter tube  139  to provide stabilization and support for the deployed inflatable parachute airbag assembly  200  and the aerial vehicle  151 . 
         [0101]    In various implementations, one end of the support straps  144   a - 144   b  connects to the housing  143 , which is connected to the aerial vehicle  151 . In other implementations, the support straps  144   a - 144   b  may be directly connected to the aerial vehicle  151  rather than to the housing  143 . The other end of the support straps  144   a - 144   b  connects to the parachute material (not illustrated), which is illustrated in  FIG. 14B . In other implementations, the support straps  144   a - 144   b  may be connected to some of the support tubes  140   c,    140   d,    140   f,  and  140   g  such that the support straps are distributed substantially evenly and radially around the center axis of the perimeter tube  139 . 
         [0102]    As illustrated in  FIG. 14B , the support straps  144   a - 144   b  connect to the parachute material  149  while the aperture at the center axis of the perimeter tube  139  is open to allow air to flow into the inflatable parachute airbag assembly  200  and create drag on the parachute material  149 . 
         [0103]      FIGS. 15A-15C  are various views of an inflatable parachute airbag assembly  300 . The inflatable parachute airbag assembly  300  is an alternative implementation of the inflatable parachute airbag assembly  200  illustrated in  FIG. 9 . The inflatable parachute airbag assembly  300  includes a plurality of support tubes  152   a - 152   h,  a main fill tube  154 , a perimeter tube  150 , and a hub  153 , which are variations of the plurality of support tubes  140   a - 140   h,  the main fill tube  146 , the perimeter tube  139 , and the top hub  145  illustrated in  FIG. 9 , respectively. 
         [0104]    The main fill tube  154  is connected to and in fluid communication between an inflation mechanism (not shown) and the hub  153 . The main fill tube  154  is operative as an input tube to the hub  153  such that gas passes from the inflation mechanism to the hub  153 . 
         [0105]    Similar to that which is described above in conjunction with  FIG. 9 , each of the support tubes  152   a - 152   h  is positioned between the hub  153  and the perimeter tube  150 . The plurality of support tubes  152   a - 152   h  are connected to and in fluid communication with the hub  153 . The hub  153  is operative to distribute gas from the main fill tube  154  into the plurality of support tubes  152   a - 152   h.  The hub  153  also acts as a central location for the plurality of support tubes  152   a - 152   h  to be connected. It should be noted that the hub  153  may be a variety of different shapes or structures. For example, the hub  153  may be a ring or annulus, a square, a triangle, a pentagon, an octagon, or other shape that is operative to connect to and inflate the support tubes  152   a - 152   h.    
         [0106]    The plurality of support tubes  152   a - 152   h  are also connected to and in fluid communication with the perimeter tube  150 . At least some of the plurality of support tubes  152   a - 152   h  are operative to inflate the perimeter tube  150 . In this implementation, the perimeter tube  150  is octagonal, rather than annulus as illustrated in  FIG. 9 . 
         [0107]    The support tubes  152   a - 152   h  may be symmetrically positioned radially around a central axis of the perimeter tube  150 . In some implementations, each of the support tubes  152   a - 152   h  may be positioned at each vertex of the perimeter tube  150 . However, implementations are not so limited, and other configurations of support tubes may be implemented. For example, the support tubes may connect to a center of each edge, rather than the vertices. The resulting structure of the inflatable parachute airbag assembly  300  is a concave-like structure that, when covered by a parachute material, can create drag when the inflatable parachute airbag assembly  300  is deployed from an aerial vehicle. 
         [0108]    Although not illustrated in  FIGS. 15A-15C , for clarity of the figures, the inflatable parachute airbag assembly  300  also includes a parachute material. The parachute material would be similar to the parachute material  129  on the top portion  127  of the inflatable parachute airbag assembly  100 B in  FIG. 3B . The parachute material can be positioned and connect to the support tubes on the outside or inside of the support tubes relative to the main fill tube such that air pushes against the parachute material when deployed. It should be noted that no parachute material is positioned planar to and inside the central opening of the perimeter tube  150 . The parachute material can be any of a variety of lightweight materials that can be used to create drag. 
         [0109]    When deployed, the system includes an inflation mechanism that provides gas to the main fill tube  154 , which distributes the gas to the hub  153 . By distributing the gas to the main fill tube  146  and the hub  153  first, the inflatable parachute airbag assembly  300  is pushed in a direction of the hub  153 , which pushes the inflatable parachute airbag assembly  300  and the aerial vehicle away from each other—creating an initial separation between the aerial vehicle and the hub  153 . The main fill tube  154  then inflates the support tubes  152   a - 152   h,  via the hub  153 , and the perimeter tube  150 , via the support tubes. The initial separation of the aerial vehicle and the hub  153  allows for the support tubes  152   a - 152   h  and the perimeter tube  150  to fully inflate such that the inflatable parachute airbag assembly  300  deploys without interference by the aerial vehicle. Air can then flow through a central opening of the perimeter tube  150  and into the concave-like structure created by the support tubes  152   a - 152   h,  which creates drag on the parachute material. This drag slows the descent of the aerial vehicle, which can reduce damage to objects or people on the ground, as well as to the aerial vehicle itself. 
         [0110]    Although not illustrated, the inflatable parachute airbag assembly  300  may also include bottom fill tubes similar to what is described above in conjunction with  FIGS. 3A-3C  so as to encase an aerial vehicle upon deployment. 
         [0111]    It should be noted that a left view, right view, and back view of the inflatable parachute airbag assembly  300  would substantially mimic the front view illustrated in  FIG. 15C . 
         [0112]      FIGS. 16A-16C  are various views of an inflatable parachute airbag assembly  400 . The inflatable parachute airbag assembly  400  is an alternative implementation of the inflatable parachute airbag assembly  300  illustrated in  FIGS. 15A-15C . The inflatable parachute airbag assembly  400  includes a plurality of support tubes  156   a - 156   h,  a main fill tube  159 , a perimeter tube  155 , and a top hub  157 , which are variations of the plurality of support tubes  152   a - 152   h,  the main fill tube  154 , the perimeter tube  150 , and the hub  153  illustrated in  FIG. 9 , respectively. And similar to the implementations in of the inflatable parachute airbag assembly  200  illustrated in  FIG. 9 , the inflatable parachute airbag assembly  400  also includes a bottom hub  158  and a plurality of fill tubes  160   a - 160   h,  which are variations of the bottom hub  147  and the plurality of fill tubes  142   a - 142   h  illustrated in  FIG. 9 , respectively. 
         [0113]    All of these components have features and functionality similar to what is described above, and will not be completely reiterated here. Briefly, however, when deployed from an aerial vehicle, an inflation mechanism provides gas to the bottom hub  158 . The bottom hub  158  distributes the gas to the main fill tube  159  and to the plurality of fill tubes  160   a - 160   h.  The main fill tube  154  provides the gas to the top hub  157 , which distributes the gas to the support tubes  156   a - 156   h.  Similarly, the plurality of fill tubes  160   a - 160   h  provide gas to respective support tubes of the plurality of support tubes  156   a - 156   h.  The perimeter tube  160  is inflated via the plurality of support tubes  156   a - 156   h.    
         [0114]    It should be noted that although not illustrated in  FIGS. 16A-16C , for clarity of the figures, the inflatable parachute airbag assembly  400  also includes a parachute material. The parachute material would be similar to the parachute material  129  on the top portion  127  of the inflatable parachute airbag assembly  100 B in  FIG. 3B . The parachute material can be positioned and connect to the outside or inside of the support tubes relative to the main fill tube such that air pushes against the parachute material when deployed. The parachute material can be any of a variety of lightweight materials that can be used to create drag. When deployed, air can then flow through a central opening of the perimeter tube  155  and into the concave-like structure created by the support tubes  156   a - 156   h,  which creates drag on the attached parachute material. 
         [0115]    It should be noted that a left view, right view, and back view of the inflatable parachute airbag assembly  400  would substantially mimic the front view illustrated in  FIG. 16C . 
         [0116]      FIGS. 17A-17E  are various views of an inflatable parachute airbag assembly  500 . The inflatable parachute airbag assembly  500  is an alternative implementation of the inflatable parachute airbag assembly  100 A illustrated in  FIG. 3A . The inflatable parachute airbag assembly  500  includes a plurality of top support tubes  166   a - 166   d,  a main fill tube  163 , a perimeter tube  162 , and a hub  164 , which are variations of the plurality of top support tubes  120   a - 120   h,  the main fill tube  122 , the perimeter tube  121 , and the top hub  117  illustrated in  FIG. 3A , respectively. 
         [0117]    The main fill tube  163  is connected to and in fluid communication between an inflation mechanism (not shown) and the hub  164 . The main fill tube  163  is operative as an input tube to the hub  164  such that gas passes from the inflation mechanism to the hub  164 . 
         [0118]    Similar to that which is described above in conjunction with  FIG. 3A , each of the top support tubes  166   a - 166   d  is positioned between the hub  164  and the perimeter tube  162 . In this implementation, the perimeter tube  162  may be a square comprising multiple perimeter tubes  162   a - 162   d,  unlike the annulus shape of the perimeter tube  121  in  FIG. 3A . As illustrated, the top support tubes  166   a,    166   b,    166   c,  and  166   d  connect between the hub  164  and the perimeter tube  162   d,    162   c,    162   b,  and  162   a,  respectively. 
         [0119]    The plurality of top support tubes  166   a - 166   d  are connected to and in fluid communication with the hub  164 . The hub  164  is operative to distribute gas from the main fill tube  163  into the plurality of top support tubes  166   a - 166   d.  The plurality of top support tubes  166   a - 166   d  are also connected to and in fluid communication with the perimeter tubes  162   a - 162   d.    
         [0120]    The top support tubes  166   a - 166   d  are symmetrically positioned, with one top support tube connecting to each perimeter tube  162   a - 162   d  radially around a central axis of the perimeter tube. The resulting structure of the inflatable parachute airbag assembly  500  is a concave-like structure that, when covered by a parachute material (not illustrated), can create drag when the inflatable parachute airbag assembly  500  is deployed from an aerial vehicle. 
         [0121]    The inflatable parachute airbag assembly  500  also includes a plurality of bottom support tubes  167   a - 167   c  and  168   a - 168   c.  A first end of the bottom support tubes  167   a - 167   c  are connected to and in fluid communication with the perimeter tubes  162   d,    162   c,  and  162   b,  respectively. The other end of the bottom support tubes  167   a - 167   c  are connected to one another, such as at another hub  169 . Similarly, a first end of the bottom support tubes  168   a - 168   c  are connected to and are in fluid communication with the perimeter tubes  162   b,    162   a,  and  162   d,  respectively. The other end of the bottom support tubes  168   a - 168   c  are connected to one another, such as at another hub  173 . The bottom support tubes  167   a - 167   c  and the bottom support tubes  168   a - 168   c  inflate in such a way that the hubs  169  and  173  move in opposite directions of each other (e.g., increasing the void between them during the inflation process), enabling the inflatable parachute airbag assembly  500  to inflate and envelop the aerial vehicle in a mouth-like fashion before coming back together (e.g., decreasing the void between them once substantially inflated). Once fully inflated, the hubs  169  and  173  are positioned adjacent to one another, similar to what is described above. 
         [0122]    Although not illustrated in  FIGS. 17A-17E , for clarity of the figures, the inflatable parachute airbag assembly  500  also includes a parachute material. The parachute material would be similar to the parachute material  129  on the top portion  127  of the inflatable parachute airbag assembly  100 B in  FIG. 3B . The parachute material can be positioned and connect to an outside or inside of the top support tubes  166   a - 166   d  relative to the main fill tube  163  such that air pushes against the parachute material when deployed. The parachute material can be any of a variety of lightweight materials that can be used to create drag. 
         [0123]    When deployed, the inflation mechanism provides gas to the main fill tube  163 , which distributes the gas to the hub  164 . By distributing the gas to the main fill tube  163  and the hub  164  first, the inflatable parachute airbag assembly  500  is pushed in a direction of the hub  164 , which pushes the inflatable parachute airbag assembly  500  and the aerial vehicle away from each other—creating an initial separation between the aerial vehicle and the hub  164 . The main fill tube  164  then inflates the top support tubes  166   a - 166   d,  via the hub  164 , and the perimeter tubes  162   a - 162   d  via the respectively connected top support tubes  166   a - 166   d.  The initial separation of the aerial vehicle and the hub  164  allows for the top support tubes  166   a - 166   d,  the bottom support tubes  167   a - 167   c  and  168   a - 168   c,  and the perimeter tubes  162   a - 162   d  to fully inflate such that the inflatable parachute airbag assembly  500  deploys around and encases the aerial vehicle without interference by the aerial vehicle. Air can then flow between the bottom support tubes  167   a - 167   c  and  168   a - 168   c  and into the concave-like structure created by the top support tubes  166   a - 166   d,  which creates drag on the parachute material. 
         [0124]    Similarly, the inflatable parachute airbag assembly  500  may also include support straps (not illustrated) similar to those described above. These support straps provide stability and support for connecting the inflatable parachute airbag assembly  500  to an aerial vehicle. 
         [0125]    Additionally, a back view of the inflatable parachute airbag assembly  500  would substantially mirror the front view illustrated in  FIG. 17D , and a left view of the inflatable parachute airbag assembly  500  would substantially mirror the right view illustrated in  FIG. 17E . 
         [0126]      FIGS. 18A-18C  are various views of an inflatable parachute airbag assembly  600 . The inflatable parachute airbag assembly  600  is an alternative implementation of the inflatable parachute airbag assembly  500  illustrated in  FIGS. 17A-17C . The inflatable parachute airbag assembly  600  includes a plurality of top support tubes  170   a - 170   d,  a main fill tube  175 , a perimeter tube  174 , a top hub  176 , and a plurality of bottom support tubes  178   a - 178   c  and  179   a - 179   c,  which are variations of the plurality of top support tubes  166   a - 166   d,  a main fill tube  163 , the perimeter tube  162 , the hub  167 , and the plurality of bottom support tubes  167   a - 167   c  and  168   a - 168   c  illustrated in  FIG. 17A , respectively. And similar to the implementations of the inflatable parachute airbag assembly  100 A illustrated in  FIG. 3A , the inflatable parachute airbag assembly  600  also includes a bottom hub  177  and a plurality of fill tubes  172   a - 172   d,  which are variations of the bottom hub  119  and the plurality of fill tubes  124   a - 124   h  illustrated in  FIG. 3A , respectively. 
         [0127]    All of these components have features and functionality similar to what is described above, and will not be completely reiterated here. Briefly, however, when deployed from an aerial vehicle, an inflation mechanism provides gas to the bottom hub  177 . The bottom hub  177  distributes the gas to the main fill tube  175  and to the plurality of fill tubes  172   a - 172   d.  The main fill tube  175  provides the gas to the top hub  176 , which distributes the gas to the top support tubes  170   a - 170   d.  Similarly, the plurality of fill tubes  172   a - 172   d  provide gas to respective support tubes of the plurality of top support tubes  170   a - 170   d.  Each of the perimeter tubes  174   a - 174   d  is inflated via the respectively connected support tube of the plurality of top support tubes  170   a - 170   d.    
         [0128]    It should be noted that although not illustrated in  FIGS. 18A-18C , for clarity of the figures, the inflatable parachute airbag assembly  600  also includes a parachute material. The parachute material would be similar to the parachute material  129  on the top portion  127  of the inflatable parachute airbag assembly  100 B in  FIG. 3B . The parachute material can be positioned and connect to an outside or inside of the top support tubes  170   a - 170   d  relative to the main fill tube  175  such that air pushes against the parachute material when deployed. The parachute material can be any of a variety of lightweight materials that can be used to create drag. 
         [0129]    Similarly, the inflatable parachute airbag assembly  600  may also include support straps (not illustrated) similar to those described above. These support straps provide stability and support for connecting the inflatable parachute airbag assembly  600  to an aerial vehicle. 
         [0130]    It should be noted that a top and bottom views of the inflatable parachute airbag assembly  600  would substantially resemble the top and bottom views of the inflatable parachute airbag assembly  500  shown in  FIGS. 17B and 17C , respectively. Additionally, a back view of the inflatable parachute airbag assembly  600  would substantially mirror the front view illustrated in  FIG. 18B , and a left view of the inflatable parachute airbag assembly  600  would substantially mirror the right view illustrated in  FIG. 18C . 
         [0131]      FIGS. 19A-19B  are various views of an inflatable parachute airbag assembly  187 .  FIG. 19A  is a side view of the inflatable parachute airbag assembly  187 , and  FIG. 19B  is a top view of the inflatable parachute airbag assembly  187  (although a bottom view would be substantially similar to  FIG. 19B ). The inflatable parachute airbag assembly  187  includes parachute material  193  connected at its periphery to a perimeter tube  190  (similar to perimeter tube  139  in  FIG. 9 ). The parachute material  193  is in a dome or semispheric shape to create a concave-like structure, similar to what is described elsewhere herein. The parachute material  193  includes two layers of air-tight material that are attached to one another to create and embed a plurality of cavities  191  between the layers of material. The cavities  191  are tube-like structures operable of being inflated and pressurized—similar to the support tubes  140   a - 140   h  in  FIG. 9 —when the inflatable parachute airbag assembly  187  is deployed from an aerial vehicle. Each of the cavities  191  are in fluid communication with each other at a hub  192  (which is also created by a cavity between different layers of the parachute material  193 ), expand radially from the hub  192 , and are in fluid communication with the perimeter tube  190  at junctions  194 . In some implementations, the hub  192 , cavities  191 , and the perimeter tube  190  are inflated via a main fill tube  189  similar to main fill tube  146  in  FIG. 9 . 
         [0132]      FIGS. 20A-20B  are various views of an inflatable parachute airbag assembly  188 .  FIG. 20A  is a side view of the inflatable parachute airbag assembly  188 , and  FIG. 20B  is a top view of the inflatable parachute airbag assembly  188  (although a bottom view would be substantially similar to  FIG. 20B ). The inflatable parachute airbag assembly  188  is similar to what is described above with the inflatable parachute airbag assembly  187  in  FIGS. 19A-19B , but with a perimeter tube  197  embedded into parachute material  198  similar to cavities  196 . The parachute material  198  is in a dome or semispheric shape to create a concave-like structure, similar to what is described elsewhere herein. The parachute material  198  includes two layers of air-tight material that are attached to one another to create and embed a plurality of cavities  196  and the perimeter tube  197  between the layers of material. The cavities  196  are tube-like structures operable of being inflated and pressurized—similar to the cavities  191  in  FIGS. 19A-19B —when the inflatable parachute airbag assembly  188  is deployed from an aerial vehicle. Each of the cavities  196  are in fluid communication with each other at a hub  195  (which is also created by a cavity between different layers of the parachute material  198 ), expand radially from the hub  195 , and are in fluid communication with the perimeter tube  197 . In some implementations, the hub  195 , cavities  196 , and the perimeter tube  197  are inflated via a main fill tube  199 , similar to main fill tube  189  in  FIG. 19B . 
         [0133]      FIGS. 21A and 21B  illustrate the deployment of an inflatable parachute airbag assembly. For ease of illustration, only a main fill tube  180 , two support straps  184   a - 184   b,  and parachute material  186  are shown—support tubes, perimeter tubes, and other components of the inflatable parachute airbag assembly and system are not shown. It should be noted that this deployment of the support straps could be utilized with any of the various implementations of the inflatable parachute airbag systems described herein. Also, additional support straps than what is illustrated may be employed. 
         [0134]    The main fill tube  180 , the support straps  184   a - 184   b,  and the parachute material  186  may be variations of the main fill tube  122 , the support straps  132   a - 132   b,  and the parachute material  129  in  FIGS. 8A-8B , respectively. The support straps  184   a - 184   b  are connected between a housing  185  (which may be a variation of the housing  131  in  FIG. 8A ) and the parachute material  186 . 
         [0135]    The main fill tube  180  includes a connection mechanism  182  for removably coupling the support straps  132   a - 132   b  to the main fill tube. In some implementations, the connection mechanism  182  is a hook and loop connection, where the hook-connection (or loop-connection) portion is connected to the main fill tube  180  and the loop-connection (or hook-connection) portion is connected to the support straps  132   a - 132   b.  However, other connection mechanism  182  may also be utilized, such as adhesives, static electricity, etc. 
         [0136]    As described herein, gas from an inflation mechanism (not illustrated) inflates the main fill tube  180  and multiple support tubes (not illustrated). As the main fill tube  180  and the support tubes inflate the inflatable parachute airbag expands and the parachute material  186  spreads out from the main fill tube  180 . This spreading of the parachute material  186  causes stress on the connection mechanism  182  between the main fill tube  180  and the support straps  184   a - 184   b.  The stress on the connection mechanism  182  increases as the parachute material  186  continues to spread out from the main fill tube  180 , which results in a peeling separation of the support straps  184  from the main fill tube  180 . The more the parachute material  186  is spread out due to the inflation of the inflatable parachute airbag assembly, the more the support straps  184  separate from the main fill tube  180 . Accordingly, as the parachute material  186   a  spreads away from the main fill tube  180 , the support strap  184   a  is peeled away from the connection mechanism  182   a.  Simultaneously, as the parachute material  186   b  spreads away from the main fill tube  180 , the support strap  184   b  is peeled away from the connection mechanism  182   b.    
         [0137]    Once the inflatable parachute airbag assembly is fully inflated, the support straps  184  are no longer attached to the main fill tube  180  but are expanded and support the force of drag on the parachute material and the inflatable parachute airbag assembly. 
         [0138]    It should be noted that a similar connection mechanism can be used if the support straps are coupled to the aerial vehicle or to the support tubes of the inflatable parachute airbag assembly. In such an implementation, as the support tubes inflate, the support straps would peel away and detach from the main tube in a manner similar to what is described above. 
         [0139]    These and other changes can be made to the implementations in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific implementations disclosed in the specification and the claims, but should be construed to include all possible implementations along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
