DESCRIPTION
The preferred embodiments of the present invention are illustrated by way of example below and in FIGS. 1-5. As shown in FIGS. 1-4, the dispenser pod 10 includes a dispenser chassis 100 with a chassis chamber 104, a first chassis end 105 and a second chassis end 110, a first chassis end cover 200 for covering the first chassis end 105, a second chassis end cover 300 for covering the second chassis end 110, a launch system 400, and at least one sway brace 500. The first chassis end cover 200 has at least one expendable passageway for accepting an expendable launch canister 215 such that the expendable launch canister 215 enters the chassis chamber 104. In the preferred embodiment, as shown in FIG. 3, there are two chassis chambers 104, one for a first expendable launch canister 215 and another for a second expendable launch canister 220. Correspondingly, there is a first expendable passageway 205 on the first chassis end cover 200 for accepting the first expendable launch canister 215 and a second expendable passageway 210 on the first chassis end cover 200 for accepting the second expendable launch canister 220. The launch system 400 is for expelling an expendable launch canister(s) 215, 220 from the chassis chamber(s) 104 and through the expendable passageway(s) 205, 210. The at least one sway brace 500 is for securing the expendable launch canister within the chassis chamber 104. In the preferred embodiment, there is are two first sway braces 505 and two second sway braces 500, such that the first sway braces 505 correspond to the first expendable launch canister 215, and the second sway braces 500 correspond to the second expendable launch canister 220.
In the description of the present invention, the invention will be discussed in a military environment; however, this invention can be utilized for any type of application that requires use of a dispenser pod.
In the preferred embodiment, the expendable launch canisters 215, 220 may be manufactured from fiberglass and can be expendable/disposable. Each expendable launch canister 215, 220 contains a launch system 400. In the preferred embodiment, the launch system 400 includes a cartridge actuated piston, an electrical harness, and a shear screw retainer system used to expel the expendable when actuated. However, any type of launch system that is practicable may be utilized.
The dispenser pod 10 may also include a dispenser pod heating system 600. The heating system 600 allows the dispenser pod 10 to maintain the expendable launch canisters 215, 220 between −34 degrees C. and 71 degrees C. As shown in FIGS. 2, 3, and 4, within each chassis chamber 104 there is a heating system 600 corresponding to each expendable launch canister 215, 220. In the preferred embodiment, each heating system 600 includes four heating elements 601 and a corresponding heat sink 602. The heating elements 601 and heat sinks 602 sets are disposed on opposite sides of the expendable launch canister, as shown in FIGS. 2 through 4, and are stacked on top of each other, with the heat sink 602 on top of the heating element 601. In the preferred embodiment, each heating element 601 is a wire resistor encased in a thin rectangular silicon rubber mat. Each mat is covered by an extruded aluminum finned heat sink 602. The heating elements 601 produce and conduct heat, while the heat sinks 602 transfer the heat to the surrounding air within the chassis chamber 104 such that a certain temperature is maintained in the chassis chamber 104.
The dispenser pod 10 may also include thermostatic control switches, thermostatic safety switches, and relays. These components may communicate with an exterior control panel that may be installed in an aircraft at a sensor station. The control panel may include a heater power switch, a panel dimmer, system circuit breakers, a reset switch, and/or a hot/cold indicator.
As shown in FIGS. 2, 3 and 4, the dispenser pod 10 may also include an electrical tray 700. The electrical tray 700 is able to electrically support bus interference wiring and the heating systems 600. In the preferred embodiment, each chassis chamber 104 includes a corresponding electrical tray 700. Each electrical tray 700 is designed to support store bus wiring and a heating system 600. Each electrical tray 700 may have a disconnect which allows it to be removed from the dispenser pod 10 for separate assembly and maintenance. Each electrical tray 700 may also include a fan 603 disposed near the heating elements 601 such that the fan 603 can circulate the air within the chassis chamber 104. In the preferred embodiment, each electrical tray 700 may include the heating elements 601 and the fan 603 integrated within. As seen in FIG. 4, the electrical tray 700 may be curved.
In the preferred embodiment, a rail assembly 800 is disposed within each chassis chamber 104. The expendable launch canisters ride along the rail assembly 800 such that when actuated each expendable launch canister(s) passes through its corresponding expendable passageway and out the dispenser pod 10. As seen in FIGS. 4 and 5, each expendable launch canister 215, 220 may include a set of yokes 230. The yokes 230 correspond to the rail assembly 800. As seen in FIG. 5, each sway brace 500, 505 includes a head 510, a screw portion 520, and a pawl 530. The head 510 is disposed outside the dispenser chassis 100, while the screw portion 520 passes through the dispenser chamber 100, and the chassis chamber 104, then aligned with the rail assembly 800 such that end of the screw portion 520 corresponds to the pawl 530 which presses on the yoke 230, such that the expendable canisters can be more tightly or less tightly secured within the chamber chassis 104.
When introducing elements of the present invention or the preferred embodiment(s) thereof, the articles “a,” “an,” “the,” and “said” are intended to mean there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, other embodiments are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred embodiment(s) contained herein.
