A folding wing comprises a fixed section, a folding section, and a latch system for latching the folding section to the fixed section. The latch system includes a plurality of latch pins, and a corresponding plurality of non-backdriveable mechanical actuators for extending the latch pins to engage the folding section.

System for latching and locking a folding wing

A wing fold system of a wing of an aircraft. The system may include a first lock of a latch to prevent movement of a latch pin of the latch to prevent movement of an unfixed portion of the wing with respect to a fixed portion of the wing, the first lock may include a first cam configured to prevent the second lock from transitioning to a second engaged position until the first lock may be in a first engaged position via contact with a second cam of the second lock. A second lock of the latch, the second lock may include the second cam configured to prevent the first lock from transitioning away from the first engaged position until the second lock transitions away from the second engaged position.

Wing fold system with latch pins through multiple mating lugs

A method and apparatus for aligning a swing tail cargo door. An alignment system comprises an alignment ramp, a set of pull-in hook mechanisms, and a set of lock trains. The alignment ramp may be configured for initial alignment between a swing tail cargo door and an aircraft fuselage during closing of the swing tail cargo door. The set of pull-in hook mechanisms may be disposed along an interface between the swing tail cargo door and the aircraft fuselage and may be capable of a final alignment between the swing tail cargo door and the aircraft fuselage during the closing of the swing tail cargo door. The set of lock trains may be disposed along the interface and may be capable of locking a plurality of latch actuators in the latched position.
