Patent ID: 8127656

Claim:
A pneumatic launch system comprising an eject valve for forcibly ejecting a store from an aircraft, a hook release valve for releasing a hook of the store, wherein the eject valve communicates with the hook release valve to actuate the hook release valve for releasing the hook; and a pressurized vessel in fluid communications with the eject valve for setting a pressure level of fluid in the eject valve at a pressure level of the pressurized vessel, wherein the pressure level of the fluid in the eject valve actuates the hook release valve to release the hook, and releases fluid to sequentially eject the store; wherein the hook release valve includes a piston having high and low sides, and the fluid in the eject valve is directed to the high side of the piston, forcing the piston to interact with a hook release mechanism to release the hook, and movement of the piston opens a port for fluid flow to ejector cylinders for ejecting the store.
