FLIGHT VEHICLE Russian patent published in 2011 - IPC B64C27/00 B64C27/06 

FIELD: transport.

SUBSTANCE: invention relates to rotary-wing flight vehicles, particularly, to helicopters. VTOL flight vehicle comprise ICE, clutch with power gear, hollow drive shaft with rotor, swash plate, control board, tail rotor and exhaust pipe with fluid evaporator. Primary engine is made up of three-guide vane two-stroke dual-action ICE with common crankshaft running through inner chamber of three guide vanes arranged in working chambers with exhaust openings. Guide vanes are intercommunicated by common exhaust pipe provided with evaporator of fluid for exhaust gas cleaning. Crankshaft incorporates p.t.o.-extensions arranged on its both sides. RH extension serves to articulate crankshaft via clutch with reduction gearbox. The latter transmits rotation to rotor driven shaft and tail rotor. Crankshaft LH extension accommodates motor clawlike rotor, said motor being made up of generator with annular winding. Rotor annular winding output terminals interact with collector rings and are connected to flight vehicle common electric circuit contacts. Rotor loop-shaped vanes are made from light strong material. Swash plate is made up of rockers articulated on rotor shaft, weights being secured on rocker ends. When electromagnets interact with magnetic field, rockers deflect to vary rotor pitch.

EFFECT: reduced noise and weight, higher engine output and rotor thrust, exhaust gas cleaning.
