DYNAMIC SUPPORT CRAFT Russian patent published in 2003 - IPC

FIELD: vertical take-off and landing aircraft and amphibians. SUBSTANCE: proposed craft has body with hollow sides, air intakes and bottom, water transportation and sprinkling system, flexible guard and pulsejet engines. Proposed pulsejet engines are installed in body bottom on hinge joints being uniformly spaced in bottom. Engines are made with diffuser and gas distributing mechanism in form of multiple-vane screw and central body with concave front surface and are provided with combustion chambers and cooling jackets with series-mounted combination nozzles and electric detonators. Combustion chambers communicate with conical adapter part and exhaust pipe with de Laval nozzle. Craft contains also system for delivery and transportation of hydrocarbon fuel, concentrated strong solution of electrolyte and electric discharge initiation system. Additional nozzles can be installed in combustion chamber, and electrodes and external magnet should be installed in expanding part of exhaust tube - de Laval nozzle. Craft can be furnished with combination nozzles with branch pipes cylindrical screws inside, adjoining channels in dielectric housing with central electrodes, nozzles and explosion chamber. Said chamber communicates at one side with orifices of combination nozzle and at other side, with combustion chamber of engine. EFFECT: reduced power consumption for keeping craft dynamically over surface. 6 cl, 9 dwg
