DEVICE TO FASTEN CARGO IN AND DROP FREE IT FROM AIRCRAFT Russian patent published in 2010 - IPC B64D1/02 B64C1/00 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly to aircraft equipment that allows cargo detachment, catapulting or dropping free. Proposed device comprises front and rear fasteners representing pneumatic cylinders secured in aircraft. Pneumatic cylinder head-end chambers are communicated with self-contained pyrotechnical devices of compressed air feed. Cargo to be dropped free comprises fastening brackets, while rods outer ends have threaded joints for securing the brackets. Note here that said cargo has contact surfaces to thrust against aircraft structure on tightening said threaded joints. Rods are fixed by fasteners that allow their release by travel of pistons driven by compressed air and their detachment together with the cargo. Front assembly can impart impulse of larger force to cargo than that imparted by rear assembly. Note here that cargo fastening brackets and one of said rods are furnished with hinges with their rotational axes perpendicular to pushing away plane.

EFFECT: safe separation of cargo without notable increase in overall dimensions and weight of proposed device.
