DYNAMIC AIR CUSHION AMPHIBIOUS VEHICLE Russian patent published in 2005 - IPC

FIELD: shipbuilding.

SUBSTANCE: invention relates to amphibious vehicles on dynamic air cushion. Proposed vehicle has platform-wing rectangular in plan with aspect ratio at 0.3-0.4 of its length, flap in aft part and interceptor on lower surface installed for deflecting downwards and with axle of rotation arranged at a distance not exceeding 0.7 of its length from force edge of platform. Three-dimensional skegs of vehicle are installed at end faces of platform parallel to its longitudinal axis, and vertical control surfaces are located in aft part of skegs. Elastic air bottles are installed on lower surface of each skeg. Wheel house of vehicle is found on upper surface of platform in its diametral part. Gas-turbine (turbofan) blow-under engines and thrust engines are mounted, respectively, in fore and aft parts of each skeg. Blow-under engines are furnished with tubular exhaust unit pointed to fore part of vehicle. Front part of exhaust unit is located before platform, being made parallel to its fore edge and equipped with nozzles deflecting in vertical plane, installed parallel to longitudinal axis of platform and secured on beam-pylon resting on fore parts of skegs Nozzle exit sections are located before fore edge of platform at distance not less than 0.15 of its length. Exhaust unit of thrust engine is provided with nozzles installed for turning in horizontal plane.

EFFECT: improved maneuverability of vehicle at optimum arrangement of interceptor in length and turning of nozzles of exhaust unit of thrust engine in horizontal plane.
