DEVICE FOR TRANSPORTATION OF CARGO BY HELICOPTER Russian patent published in 2007 - IPC B64D9/00 

FIELD: aeronautical engineering; devices for transportation of cargo in helicopter external store.

SUBSTANCE: proposed device includes container inform of parallelepiped with two tail stabilizers and set of lines of external store connected with helicopter lock. Used as stabilizers are two swivel flaps secured on rear end face of container by means of lag hinges mounted on side surfaces of container. Swivel flaps may be either secured in plane of rear end face during storage or may be turned and secured in open position at angle of 120 to 180° to side walls of container before flight. Swivel flaps are sectional in construction and are provided with additional plates attached by means of lag hinges or without them. Additional plates make it possible to perform more fine adjustment of air incoming flow for longitudinal stability of container in flight. Swivel flaps are fixed in open position by means of rods which are adjustable in length. Lines of helicopter external store have different length: lines secured near rear end face are longer as compared with those secured at front end face, thus ensuring inclination of container longitudinal axis to level at angle of 10 to 35° at hovering.

EFFECT: improved flight characteristics of helicopter.
