HELICOPTER EXTERNAL STORE SYSTEM Russian patent published in 2000 - IPC

FIELD: aeronautical engineering; stabilization of cargoes in external store. SUBSTANCE: proposed system includes cargo carrying member whose vertical rod is connected with helicopter by means of gimbal joint for turning relative to its axis under action of drive. Connected to vertical rod by means of two flexible links is horizontal rod located under helicopter fuselage and connected with two pairs of lines secured to it. Each pair of lines is connected over edge of horizontal rod means of swinging balance beams, thus providing for even loading of four lines. Lower ends of lines in each pair are interconnected; they carry cargo gripping devices, such as electric locks, hooks, etc. Spacer fitted between lines in each pair at distance of 0.2 to 0.8 of their length from point of connection exclude twisting of lines in this pair. Cross-members of varying length fitted between lines of different pairs at distance of 0.2 to 0.8 of their length from points of connection with balance beams are used to exclude twisting of lines of different pairs. Proposed system ensured preset position of cargo in azimuth in maneuvering of helicopter and at dynamic loads acting on cargo in the course of mounting. EFFECT: enhanced efficiency and reliability. 5 cl, 2 dwg
