Abstract : A parachute container for aircrew ejection seats is designed with a rigid body having a reduced volume and weight, and which is hermetically sealed and filled with an inert gas to extend service life without maintenance, the container being provided with a detachable, flexible cover to permit the container to expand in volume proportional to the reduction of external atmospheric pressure. The cover is made of an elastomeric material having elastic memory capable of returning to its preformed shape as atmospheric pressure increases, repeated in operations from sea level to high altitudes.
