FLIGHT VEHICLE Russian patent published in 1995 - IPC

FIELD: flight vehicle engineering. SUBSTANCE: flight vehicle has cabin 1 provided with a landing-and-bearing mechanism, engine having blades 3 interacting with air, and control unit. Blades 3 are set on axles 4 mounted for permitting rotation in bearings 8 at their edges. Bearings 8 are secured to radial stands 9 for central shaft 10 which is coupled with engine 18. The control unit is constructed as cam surface 7 which can rotate and is mounted coaxially to central shaft 10. Levers 5 of axles 4 with blades 3 bear on the cam surface via spring 6. Central shaft 10 is positioned symmetrically with respect to cabin 1 on its sides, made as a unit member and positioned in horizontal plane. Blades 3 are shaped and area of their surface decreases in the direction of bearing 8 which is far from the housing of cabin. EFFECT: improved maneuverability, enhanced efficiency and decreased metal usage. 3 cl, 4 dwg
