Abstract For use in an aircraft having a store retaining cavity from which a loaded store may protrude beyond the envelope of the aircraft, a dual condition air bag system for substantially eliminating air turbulence about the store-cavity interface when the store is loaded, and reducing relative movement of the store during taxiing and flight of the aircraft; and for substantially eliminating air turbulence about the cavity-aircraft interface following release of the store by expansion of the air-bag to a dimension to substantially conform the exterior thereof to the envelope of the aircraft, the expanded shape of the air-bag system being controlled by a plurality of ties bonded to the inner surfaces of the air-bag to limit the displacement of the exterior surface of the air-bag when air pressure is applied to the interior thereof.

Claim 1
Independent Claim
215 words
For an aircraft having through its envelope an open section forming a cavity adapted to carry a store suspended therein by means of store release hooks which engage lugs forming a part of the store, and from which the store can be released, an improved dual condition air-bag system arranged in said cavity, comprising: an inflatable air-bag having opposing interior surfaces, one of which forms an outer surface, having a plurality of ties with each tie having one end attached to one of said interior surfaces of said air-bag and the other end of each tie being attached to another interior surface of said air-bag for causing said surfaces of said air-bag to be displaced to a positive spaced relation relative to each other upon inflation of said air bag; said air-bag being arranged in the cavity of said aircraft to permit insertion of a store into said cavity, and to cause the outer surface to be expanded into substantial conformity with the envelope of the aircraft; said air-bag having at least one air-tight passage extending through said air-bag to provide clearance for lugs of the store to pass through for engagement with the release hooks; and said air-bag system further comprising spring cleat means in said passage to automatically open and close said passage.
