Abstract

A lock for a pallet to be discharged from aircraft in flight by deploying a parachute connected to the pallet behind the aircraft. The loaded pallet or container is locked in place by one or more abutments until the tension applied by the opened parachute reaches a predetermined value. Each abutment is maintained in locked position by pressure responsive lock mechanism. This lock mechanism may be in the form of a punch and penetrable fuse plate, or a compressible or deformable fuse adapted upon predetermined loading to yield a predetermined amount. The lock mechanism is carried by a rail extended longitudinally of the aircraft which is adapted to move between an upright operating position in which it overlies an edge of a pallet, and a lowered position in which it is beneath the pallet supporting surface.
