The invention relates to an aircraft designed for air transportation, in particular helicopters.

Known methods and devices for air transportation (transportation) of goods.

For U.S. patent No. 5090639, MGI VS 1/20, R.J. IMS 33-9-93 [1] a device for packing of cargo in the passenger cabin. The device contains multiple containers that are in compliance with their weight placed on the cabin floor. The containers according to their size can pass through the passenger door of the aircraft and installed under shelf for hand Luggage. When placing one container on each side of the cabin between them is space sufficient for the passage of passengers. To install containers used rails for the passenger seat. The load distribution on the floor of the salon provides its retention within the acceptable range even when fully loaded containers. The device can accommodate passengers and Luggage in one place. This aircraft may not be used to transport helicopters, as its cargo compartment is designed for transportation of standard containers.

For transporting goods by air is applied to the plane, which has in the fuselage longitudinal cargo Bay (U.S. patent No. 5106038, IPC VS 1/22, WE 9/00, R.J. IMS 33-11-93) [2]. At one with the Auron in the front part of the fuselage has a door opening for access and transmission of the cargo container in the fuselage and in the front of the cargo compartment, intended for content standard freight containers. The rear fuselage has a ramp for access and support of cargo, drop down from the fuselage to communicating with disposable surface, providing an inclined ramp from the tail of the cargo compartment to relieve the surface. The containers are sequentially supplied to the airfield loading near the doorway and loaded into the front of the cargo compartment through the doorway, then move from the front area of the cargo compartment back to the tail section. Containers transported by air loaded in the cargo compartment to the destination aerodrome, then open the ramp to provide a slope to the unloading surface. Next consistently perform the unloading of containers.

Known methods of transport helicopters and equipment for loading, placement and mooring ensure safe transportation in accordance with the technical requirements (Provisional technical requirements for equipment and goods intended for air transportation in their IL-76) [3].

For transport helicopters pre-formed containers, stacked goods, place them in the cargo cabin, moor and do unloading after transport for the subsequent Assembly of transported helicopter is s.

FIELD: aeronautical engineering; flying vehicle equipment for transportation of cargoes in external store; performance of construction and erection jobs.

SUBSTANCE: proposed device has cross-member with cargo slings at the ends which is connected with helicopter lock by means of couplings, cross-member stabilization system provided with elastic couplings and cross-member orientation system for its orientation in horizontal plane; it is provided with drive in form of winch and actuating member - sling. Connected to one end of cross-member is main elastic coupling of stabilization system; actuating member that is winch sling is connected to opposite end of cross-member by means of several blocks. One or several blocks are mounted on opposite end of cross-member; other blocks are secured to helicopter body. Winch sling embraces blocks in turn forming tackle block; its running blocks are secured to cross-member and standing blocks are secured to helicopter body. End of sling running off tackle block is connected to additional elastic coupling whose stiffness is lesser than that of main elastic coupling, owing to which (and owing to use of tackle block) dynamic loads in cross-member drive and duration of cargo vibration are reduced at simultaneous enhancing of accuracy of erection. Elastic couplings of stabilizing system may be made in form of rubber shock absorbers or springs. Position of cargo is stabilized due to resistance forces arising in both elastic couplings in case of change of their length.

EFFECT: reduction of dynamic loads in cross-member drive; enhanced accuracy of cargo handling in azimuth in performing construction and erection jobs.

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.

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.

FIELD: aeronautical engineering; flying vehicle equipment for transportation of cargoes in external store; performance of construction and erection jobs.

SUBSTANCE: proposed device has cross-member with cargo slings at the ends which is connected with helicopter lock by means of couplings, cross-member stabilization system provided with elastic couplings and cross-member orientation system for its orientation in horizontal plane; it is provided with drive in form of winch and actuating member - sling. Connected to one end of cross-member is main elastic coupling of stabilization system; actuating member that is winch sling is connected to opposite end of cross-member by means of several blocks. One or several blocks are mounted on opposite end of cross-member; other blocks are secured to helicopter body. Winch sling embraces blocks in turn forming tackle block; its running blocks are secured to cross-member and standing blocks are secured to helicopter body. End of sling running off tackle block is connected to additional elastic coupling whose stiffness is lesser than that of main elastic coupling, owing to which (and owing to use of tackle block) dynamic loads in cross-member drive and duration of cargo vibration are reduced at simultaneous enhancing of accuracy of erection. Elastic couplings of stabilizing system may be made in form of rubber shock absorbers or springs. Position of cargo is stabilized due to resistance forces arising in both elastic couplings in case of change of their length.

EFFECT: reduction of dynamic loads in cross-member drive; enhanced accuracy of cargo handling in azimuth in performing construction and erection jobs.
