Munitions rack with structural element and insertable ejectors
A munitions rack includes a munitions rack structure that houses multiple compact ejectors. The structure includes a pair of internal longitudinal ribs, inboard of a pair of external longitudinal ribs. A spine of the munitions rack structure links all the ribs, and the munitions rack structure may be formed out of a single piece of material. The ribs define a pair of side recesses on the port and starboard sides of the bomb, which each may be further subdivided into a forward pocket and an aft pocket. Removable ejectors are located in the pockets. The ejectors may receive pressurized gas from pressurized gas source(s) located outside of the ejectors. The ejectors may each have multiple forward pistons and multiple aft pistons. The ejectors may include pitch control valving to control the relative amounts of pressurized gas sent to the forward piston(s) and aft piston(s).
1. A munitions ejector for use in a munitions rack, the munitions ejector comprising:
a pressurized gas interface for receiving pressurized gas from a pressurized gas source that is external to the munitions ejector; and
a manifold that distributes pressurized gas from the pressurized gas interface to multiple forward pistons that are used to push a forward ejector foot of the munitions ejector outward, and to multiple aft pistons that are used to push an aft ejector foot of the munitions ejector outward.
2. The munitions ejector of claim 1 ,
wherein the multiple forward pistons includes a pair of side-by-side forward pistons in a forward piston housing; and
wherein the multiple aft pistons includes a pair of side-by-side aft pistons in an aft piston housing.
3. The munitions ejector of claim 1 , wherein the manifold includes pitch control valving for selectively controlling relative amounts of pressurized gas sent to the multiple forward pistons and the multiple aft pistons.
4. The munitions ejector of claim 1 , further comprising:
a forward pusher and an aft pusher that extend to push a munition away from the munitions rack.
5. The munitions ejector of claim 4 ,
wherein the forward pusher includes the forward ejector foot for contacting and engaging the munition; and
wherein the aft pusher includes the aft ejector foot for contacting and engaging the munition.
6. The munitions ejector of claim 4 ,
wherein the forward pusher is actuated to push away the munition by the multiple forward pistons; and
wherein the aft pusher is actuated to push away the munition by the multiple aft pistons.
7. The munitions ejector of claim 6 ,
wherein the multiple forward pistons extend the forward pusher; and
wherein the multiple aft pistons extend the aft pusher.
8. The munitions ejector of claim 1 , further comprising:
a pair of hooks that are used to hold a munition in place prior to release.
9. The munitions ejector of claim 8 , wherein the hooks are retracted to release the munition as part of a launch process.
10. The munitions ejector of claim 1 , further comprising safety and release mechanisms.
11. The munitions ejector of claim 10 , wherein the safety and release mechanisms include hook latch locks.
12. The munitions ejector of claim 10 , wherein the safety and release mechanisms include a position indicator.
13. The munitions ejector of claim 10 , wherein the safety and release mechanisms include a solenoid.
14. The munitions ejector of claim 10 , wherein the safety and release mechanisms include a release mechanism lock.
15. A munitions ejector for use in a munitions rack, the munitions ejector comprising:
a pressurized gas interface for receiving pressurized gas from a pressurized gas source that is external to the munitions ejector; and
a manifold that distributes pressurized gas from the pressurized gas interface to one or more forward pistons that are used to push a forward ejector foot of the munitions ejector outward, and to one or more aft pistons that are used to push an aft ejector foot of the munitions ejector outward;
wherein the manifold includes pitch control valving to control the relative amounts of pressurized gas distributed to the one or more forward pistons and the one or more aft pistons;
wherein the one or more forward pistons includes a pair of side-by-side forward pistons in a forward piston housing; and
wherein the one or more aft pistons includes a pair of side-by-side aft pistons in an aft piston housing.
16. The munitions ejector of claim 15 , wherein the pitch control valving includes:
a forward pitch control valve for controlling flow of pressurized gas to the one or more forward pistons; and
an aft pitch control valve for controlling flow of pressurized gas to the one or more aft pistons.
17. The munitions ejector of claim 16 ,
wherein the forward pitch control valve has a through hole, with the forward pitch control valve rotated about an axis of the forward pitch control valve's center, perpendicular to a forward passage through which pressurized gas flows from the manifold to the one or more forward pistons, to control a degree of alignment between the through hole of the forward pitch control valve and the forward passage; and
wherein the aft pitch control valve has a through hole, with the aft pitch control valve rotated about an axis of the aft pitch control valve's center, perpendicular to an aft passage through which pressurized gas flows from the manifold to the one or more aft pistons, to control a degree of alignment between the through hole of the aft pitch control valve and the aft passage.
18. The munitions ejector of claim 15 , further comprising:
a pair of hooks that are used to hold a munition in place prior to release.
19. The munitions ejector of claim 18 , wherein the hooks are retracted to release the munition as part of a launch process.
