Title: Multi-Axis Parachute and Skydiving Simulator

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     Not Applicable. 
     TECHNICAL FIELD 
     The present invention relates generally to a skydiving simulator. More specifically, the present invention relates to a parachute and skydiving training module and simulator which provides multi-directional movement to accurately mimic live parachute jumps. 
     BACKGROUND 
     In recent years, commercial parachuting jumping and skydiving has become increasingly popular. The activity involved jumping from an aircraft such as a helicopter or airplane and then controlling the speed of descent by using a parachute. In order to successfully parachute jump or skydive, the jumper must first ride in an aircraft to a certain altitude and then exit the aircraft and safely make his or her way down to the terrain, releasing the parachute at the appropriate altitude. The knowledge of how to exit the aircraft, when to jump, how to control one&#39;s body, or at what altitude to deploy the parachute is required to successfully parachute jump or skydive. In order to obtain and retain this knowledge, training is required. 
     Traditional parachute jumping and skydiving training simulators involve some degree of vertical motion coupled with a harness and a visual simulation that is provided through virtual reality goggles. Traditional parachute jumping and skydiving training simulators lift the user off the ground vertically, allowing the user to remain suspended on either the x-axis or y-axis. The user may be exposed to generated air flow while wearing the virtual reality goggles. The user is vertically lowered back to the ground at the end of the training simulation. 
     While the known prior art allows users to experience a vertical landing, the users do not experience the stresses, strains, and forces of changing directions, sharp turns for landing, and swinging forces that a jumper may experience during his or her descent. By experiencing multi-axis movement with the visual simulation, a user may train more effectively in the art of skydiving. 
     Accordingly, a need exists for a new and novel multi-axis parachute and skydiving module simulator that will provide the combination of motions and simulations that will produce real parachute flight characteristics.

     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known art, the present invention relates to multi-axis parachute and skydiving module simulator that overcomes the deficiencies of the prior art. The general purpose of the present invention, which shall be described subsequently in greater detail, is to provide a novel parachute jumping and skydiving simulator that jumpers may use to experience real jump forces and simulated flight movements. 
     The features of the invention which are believed to be novel are particularly pointed out and distinctly claimed in the concluding portion of the specification. By way of a non-limiting example, the present invention provides a novel solution for a jumper to experience multi axis and physical motions when utilizing a parachute and skydiving simulator. These and other features, aspects, and advantages of the present invention will become better understood with reference to the following drawings and detailed description. 
     The present invention provides for a multi-axis parachute and skydiving module simulator that comprises of a dome housing, stabilizing shaft, radial motor, gimbal assembly, cable assembly, a plurality of sensors, a parachute harness, and a fan. In a preferred embodiment, the gimbal assembly is attached to the interior of the dome housing. The gimbal assembly, located at the proximal end of the stabilizing shaft, comprises of a radial torque motor, a motor housing, a support plate, and gimbal rings. 
     In another preferred embodiment of the present invention, the cable assembly is located as the distal end of the stabilizing shaft and comprises and electronic assembly, a rear cable lift motor, a right cable lift motor, a left cable lift motor, and the associated cable spools. The right and left cables are connected to the right and left side of the parachute harness. The rear cable is connected to the rear of the parachute harness, or, in an alternative configuration, the rear cable may be removably connected to the legs of the jumper while the present invention is in use. The harness is configured to move up and down along the z-axis. When in use, the gimbal assembly rotates the harness about the z-axis (yaw). 
     In some embodiments, the right cable lift motor is connected to the right cable spool and is configured to lift the right side of the parachute harness. The left cable lift motor is connected to the left cable spool and is configured to lift the left side of the parachute harness. The rear cable lift motor is connected to the right cable spool and is configured to lift the rear of the parachute harness or, in an alternative configuration, the legs of the jumper while the present invention is in use. A traverse motor is connected to the multi-axis plate and is configured to adjust the positions of the right lift motor and the left lift motor in unison across the multi-axis plate. The traverse motor, in conjunction with the right lift motor, the left lift motor, and the rear lift motor, create a rotation about the y-axis (pitch). 
     In another preferred embodiment of the present invention, the jumper may control his or her turning movements while using the multi-axis parachute and skydiving modular simulator by pulling either the right or left steering cables which are connected to the right and left steering motors and affixed to the multi-axis plate. While worn by the user, the parachute harness assembly will allow for the user to experience the lift movements and jump forces through parachute flying motions. Specifically, the right lift motor and the left lift motor manipulate the right and left cables which are connected to the parachute harness. This will permit the jumper to rotate about and move along the z-axis, and also create rolling motion along the x-axis by offsetting left and right lifting cables. The rear lift motor and the rear cable, when connected to the parachute harness, will permit for the user to transition from a vertical position on the y-axis to a horizontal position on the x-axis, or in other words, pitch the jumper forward or backward. The gimbal assembly allows for the cable assembly to swing radial from the dome, controlling z-axis rotation or yaw movement. The resulting varying combination of movements allow the user to move up, down, right, left and to experience radial motions. In addition, the steering cables utilized by the jumper may create commands to the right lift motor and the left lift motor to define the motion path. 
     In a preferred embodiment of the present invention, the multi-axis parachute and skydiving module simulator is controlled by a control box that may be attached to the dome housing or, in the alternative to standalone housing outside of the dome housing. In some embodiments, the control system is configured to receive and process input from the steering cables, along with the plurality of body sensors and the plurality of sensors on the parachute harness. The plurality sensors, on both the body and the harness, provide input to the control system regarding the jumper&#39;s movement and the jumper&#39;s body position. The input received by the control system will then direct the control system to lift the right lift motor, the left lift motor, and the rear lift motor. The control system will also direct the radial torque motor to rotate and move the gimbal. The combination of the rotations of the various motors of the present invention will impart movement to the modular simulator thus creating real world parachute flying movements to the jumper&#39;s body. 
     In other embodiments, the control box will display three dimensional (“3D”) graphic data to the display goggles, which will display graphics of the coordinated motion scenes. By way of non-limiting example, if the jumper moves his or her head to look down, the display will show the earth&#39;s terrain to the jumper. If the jumper moves his or her head to look up, the jumper will see the displayed image of the virtual parachute. 
     In another preferred embodiment of the present invention, a fan assembly may be used to create realistic wind forces that a jumper may experience during a parachute or skydiving activity. The fan assembly comprises of a support arm that extends from the gimbal plate frame or the interior of the dome housing, which support arm is configured to pivot to adjust wind directions. In an alternative configuration and embodiment, while the modular simulator is in use, the fan assembly support arm may extend the fan to the bottom of the jumper, move to the top of the jumper, or move to the left or the right to provide a realistic air flow experience that mimics free falling and parachute flying. 
     The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Furthermore, while the preferred embodiment of the invention has been described in terms of the components and configurations, it is understood that the invention is not intended to be limited to those specific dimensions or configurations but is to be accorded the full breadth and scope of the spirit of the invention.
