ABSTRACT:
An elongated, cylindrical case has an intermediate partition dividing it into a canister and a housing. A parachute is attached into the housing with deployment means releasable by a timer. After a predetermined time has elapsed, the timer withdraws radial pawls to release an end cap from the housing, allowing the parachute to be deployed. The canister is equipped with a special end cap capable of hermetically sealing the canister so that it may convey any of a variety of cargo via airdrop. This end cap is essentially a cylinder, recessed at both ends. A disk is held adjacent the inner end of the cylinder by a center post that passes through central holes in the cylinder by the disk and is pivoted to a plurality of radial pawls that may be extended or withdrawn by rotation of the center post, so that they may engage a shoulder in the end of the canister. The center post is equipped with means for locking it in one position so that the end cap cannot be removed by accident from the canister.
