Abstract
A dual dependent ejector assembly for ordnance stores on aircraft, etc. wh imparts to the store, in addition to normal ejecting forces, an angular rate of movement and/or an angular attitude. The ejecting forces are applied at fore and aft locations on the store (e.g. bomb) by piston-like ejectors which are actuated by hydraulic circuitry. Dual dependency is achieved by the action of a stepped piston which transmits equal volumes of fluid from two source chambers to each of the two ejectors. A third chamber in which the stepped piston operates supplements the fluid supplied to the ejectors by the first two chambers by means of a valve distribution system which includes two pressure responsive spool valves.
Claims16
A variable force, dual ejector for an aircraft weapon stores structure for imparting an angular discharge or angular rate of discharge of the store comprising:
- a store carriage means for removably carrying the stores on the aircraft;
- first and second fluid actuated ejector means for ejecting the store from the aircraft;
- a source of working fluid in effective fluid communication with said ejector means;
- said source including means forming three fluid chambers;
- a first of said chamber means being in substantially direct fluid communication with said first ejector means and the second of said chamber means being in substantially direct fluid communication with said second ejector means;
- first valve means regulating the flow of fluid from the third of said chamber means;
- second valve means in fluid communication with said first valve means for distributing the flow of fluid from said third chamber means to said first and second ejector means;
- third valve means movable between an open and a closed position for regulating the flow of fluid between said second valve means and said first ejector means;
- fourth valve means movable between an open and closed position for regulating the flow of fluid between said second valve means and said second ejector means;
- whereby depending upon the positions of said third and fourth valve means, fluid from said third fluid chamber means supplements the flow of fluid to said first and second ejector means to thereby regulate the rate and extent of travel of said first and second ejector means.
A variable force, dual ejector for a weapon stores structure adapted to be used in conjunction with a store carriage means on an aircraft for imparting an angular discharge attitude or angular rate of discharge to the store, comprising:
- fluid actuated ejector means for ejecting the store from the aircraft;
- a source of working fluid in effective fluid communication with said ejector means;
- means for fluidly interconnecting said fluid source with said ejector means;
- said fluid source including means forming a plurality of distinct fluid chamber means;
- the flow of fluid from a first of said chamber means adapted to flow primarily to a first of said ejector means and the flow of fluid from a second of said chamber means adapted to flow primarily to a second of said ejector means;
- means for distributing the flow of fluid from a third chamber means to said first and second ejector means;
- whereby said distributing means allocates the fluid from said third chamber means so as to supplement the flow of fluid to said first and second ejector means.
