FIELD: aviation; amphibian transport facilities for performing ground-effect flights, vertical takeoff, hovering and free flights.
SUBSTANCE: proposed method consists in transfer of energy from engine to propeller fan forming working medium at high parameters. When flaps are open, working medium is directed to tractive propelling nozzles and when flaps are closed, working medium is directed via gas-and-air passage to air cushion nozzles passing the streamlined aerodynamic profiles, thus forming the system of lift forces which exceed numerically mass of amphibian. When flaps of propelling nozzles are closed, working medium is accelerated in jet barrier nozzles to speeds forming the "rigid" core of jets having length of 7-8 calibers of nozzle section, thus ensuring reliable maintenance of increased pressure in air cushion chambers at altitude of 7-8 calibers of nozzle section. Center of application of lift forces is approached to center of mass and air cushion area is increased due to availability of platform in amphibian which forms sectionalized wing together with lifting wing. This platform has positive angle of attack from beneath; fuselage is located in front part; engine and supercharger complex is enclosed in cowling and is located in rear part. The amphibian is controlled with the aid of flaps located at propelling nozzle inlet, as well as with the aid of rudders and elevators located at outlet. Amphibian may be also provided with hinged cantilevers with flaps-ailerons for change of wing geometry in horizontal and vertical planes.
EFFECT: intensification of freight traffic; saving of fuel; reduction of ecological loading by several times; enhanced safety of transportation of passengers and freight at low-altitude flights.
