Cargo restraint system with spring fuse

摘要

A cargo restraint and delivery system for an aircraft having a cargo-receiving and delivery opening for cargo secured to pallets. The cargo is moved backwardly and out of the rear cargo-delivery opening under either the pull of the parachute when the aircraft is airborne or by the force developed by the rapid acceleration of the aircraft for combat off-loading of cargo onto the ground. One of two spaced-apart guide rails for the pallets supports locks to releasably hold the pallets. A logistics control includes a lever at a loadmaster station to move a logistics control cable extending along the rail supporting the locks to move them into a first position where the pallet locks will release the pallets for movement either forward or aft of the aircraft and a second position where the pallet locks will prevent either forward or aft movement of a pallet. A system of levers coupled to each of the locks is controlled by a chain system extending to the loadmaster station and operation on cam members to sequentially actuate each system of levers. The levers move the pallet locks into a third position wherein the locks will prevent forward movement of a pallet but will permit aft movement of a pallet against a biasing force of a spring acting on the lever system thereof. The control for the pallet locks is mounted below the floor of an aircraft and the guide rails are mounted to pivot the troughs to form a flush relation with the floor of the aircraft.
