Abstract
A wind driven generator includes a rotor disposed in a cylindrical duct and supported by a frame for rotation in response to wind flowing through the duct. The rotor includes plural circumferentially spaced paralleled rotor blades supported for rotation about a generally horizontal axis. Each blade is supported for pivotal movement to change blade pitch, angle of attack or camber as the rotor rotates. A pitch or camber control motor or self-governing wind vane mechanism is operable to move a circular cam to vary blade pitch or camber to control rotor speed. The duct is mounted on a mast having a base supported on a foundation for pivotal movement to face the wind for maximizing air flow through the duct. Electric power generators are connected to opposite ends of the rotor at respective power output or drive shafts.
Claims17
A wind driven power generator comprising:
- a frame;
- a rotor supported for rotation on said frame, said rotor including plural, circumferentially spaced apart elongated, generally parallel rotor blades, said rotor blades being supported by spaced apart arm assemblies, at least one of said arm assemblies including drivingly connected to a drive shaft;
- wherein said rotor includes rotor blade lifting force control means having cam followers engageable with a cam operably connected to said rotor blades, wherein each of said rotor blades is connected to a link connected to one of said cam followers, respectively, and responsive to rotation of said rotor to vary one of the pitch angle and camber of said each rotor blade with respect to the direction of wind impinging on said rotor.
