The system includes two parallel rails, multiple airdrop/logistics locks mounted by one rail, and multiple forward restraint mechanisms mounted by the other rail opposite alternate airdrop/logistics locks. Two drawbars are connected to and provide remote operation of the airdrop/logistics locks and the forward restraint mechanisms, respectively. The airdrop/logistics locks additionally are operable locally. Each airdrop/logistics lock includes a movable detent and a force responsive release assembly which releases the detent from an extended locking position upon attainment of a predetermined threshold force in the aft direction. The release assembly includes a fuse and a contractible cartridge assembly connected to the detent such that movement of the detent toward a release position will cause the cartridge to contact. The fuse is constituted by a longitudinally crushable honeycomb slug and has such load-deflection characteristics that it will crush a predetermined amount while maintaining a substantially constant resistance to further compression until attainment of a threshold force level. Each airdrop/logistics lock additionally includes an arming member which must be opened in order to permit its fuse to be crushed (for operation in an airdrop mode) and a locking member which blocks its fuse from being crushed (for operation in a logistics mode), even if the lock has been armed previously.

A cargo delivery system for aircraft, comprising: two spaced apart parallel rails adapted to support a cargo carrier for movement forward and aft parallel to the longitudinal axis of an aircraft, and at least two combination airdrop/logistics locks mounted by one of the rails to respectively engage the cargo carrier at two spaced apart locations for securing the carrier at a predetermined position along the rails, and for releasing the cargo carrier in unison upon attainment of a predetermined aft force applied to the cargo carrier by parachute means deployed behind the aircraft; each of said airdrop/logistics locks including a movable detent engageable with a cargo carrier and force responsive release means including; (a) an axially crushable force threshold element having a substantially constant resistance to deformation over a predetermined deformation range; and (b) movable deforming means acting between said element and said detent for deforming said element and for releasing said detent upon attainment of said predetermined aft force, said predetermined deformation range being sufficient to allow said element to be partially deformed without releasing said detent so as to permit aft shifting of the cargo carrier until the detent associated with a second such airdrop/logistics lock is engaged with the cargo carrier, with additional deformation of said element occuring upon attainment of said predetermined aft force. A cargo delivery system for aircraft, comprising: two spaced apart parallel rails each made up of at least two rail sections independently movable between an upright position adapted to support a cargo carrier and a stowed position adjacent a floor surface; and a plurality of lock means respectively associated with the rail sections which make up one of said rails for restraining a cargo carrier supported thereby when their associated rail sections are in their upright positions, and means for remotely operating the lock means associated with only those rail sections which are located in their upright position; whereby one set of parallel rail sections may be in their upright positions for acceptance of cargo carrier borne cargo while another set of sections may be in their stowed positions for acceptance of another type of cargo.
