Air-cushion landing gear for aircraft

The invention relates to aircraft and more particularly an air-cushion landing gear comprising a system of landing gear units suspended from an aircraft, with at least two of the units being spaced transversely with respect to the longitudinal axis of the aircraft, and one of them being arranged on the axis ahead of the aircraft center of gravity; each landing gear unit comprises a platform with an annular inflatable cell attached to its underside and used, when inflated, as a flexible curtain circumscribing an air cushion space under the platform, the inflation of each cell and the formation of the air cushion is accomplished by an independent injecting device built in the platform; the spaced-apart cells are provided with an operating device for decelerating and controlling the movement of the aircraft on the runway surface; such a design of the air-cushion landing gear makes it possible to easily and rapidly adapt modern planes and helicopters to such a landing gear with the take-off, landing and taxiing techniques being similar to those used with conventional wheeled landing gears; in addition, the proposed landing gear is more economical and simpler in manufacture and in service as compared to those of the prior art.
