Abstract: A flexible rotary coupling is provided to transfer rotary power across the wingfold access of a folding wing aircraft. The flexible rotary coupling has a step-up gear box on the inboard wing section to increase the rotational velocity of the flexible coupling. The outboard wing section has a step-down gear box to decrease the rotational velocity of the flexible coupling to that of the step-up gear box input. In this way, substantial rotational power can be transferred across the wingfold axis through the flexible coupling axis with a thin, highly flexible shaft. A guide mechanism is provided to store excess shaft length when the wing is in the unfolded (i.e., straight) position.

Abstract: 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.
