Abstract
A rotary wing aircraft is provided with longitudinally oriented counter-rotating rotors with circumferentially spaced variable pitch rotor blades connected to rotatable support rings mounted on the aircraft fuselage. Rotor downwash may be guided laterally and longitudinally by respective sets of moveable guide vanes. Propulsion may be obtained by an engine providing thrust and power take-off for driving the rotors. An auxiliary or second engine may be drivingly connected to the rotors. One embodiment includes rotors with lift or blade pitch angle control mechanism for changing the resultant lift forces for providing aircraft lateral movement and movement about a yaw axis. A wind driven power turbine includes a similar pitch angle control mechanism.
Claims33
A rotary wing aircraft comprising:
- a fuselage;
- spaced apart counter-rotating rotors mounted on said fuselage for rotation in opposite directions, said rotors including plural, circumferentially spaced apart, longitudinally extending rotor blades supported for change in pitch or angle of attack during rotation thereof to provide lifting effect for said aircraft;
- and
- engine means driveably connected to said rotors.
A wind driven power turbine comprising:
- a rotor support mast;
- a rotor supported for rotation on said mast, said rotor including plural, circumferentially spaced apart longitudinally extending rotor blades supported for change in pitch or angle of attack during rotation thereof, said rotor blades being supported by spaced apart sets of circumferentially spaced radially extending blade support arms, each set of arms including a hub portion, at least one of said hub portions being drivingly connected to a driveshaft.
