Abstract

An aircraft aerial cargo delivery system for aircraft having a rear cargo receiving and delivery opening and ramp. Cargo is ordinarily secured to pallets which move backwardly and out of the rear cargo delivery opening under either the pull of a parachute when the aircraft is airborne or under the influence of rapid acceleration of the aircraft during a rapid (i.e., combat off-load) discharge of the cargo onto the ground. Locks must be provided (1) which will positively retract (unlock) for ground loading of pallets, (2) which will secure the pallets against forward or aft movement during normal flight conditions, (3) which will permit free aft movement but not forward movement only during combat off-load conditions, and (4) which will permit, through the use of a metallic fuse, aft movement only after a parachute connected to the pallet opens and exerts a predetermined force on the pallet sufficient to overcome the resistance presented by the fuse. The present invention provides locks for the pallets which combine all of the foregoing functions, which can be incorporated into one of two restraint rails on which the pallets are positioned, and which can be controlled by a single control rod at the load master station of the aircraft.
