Abstract
An improved wind-powered generator, comprising a wind wheel with semi-flexible sails, a supporting tower that can rotate freely with the wind direction, a fairing that ensures the wind wheel is always downwind of the tower, energy generators affixed to the upper tower and mechanically coupled to the rim of the wind wheel, and a controller that changes the angle of attack of the wings.
Claims10
A wind turbine comprising:
- a support tower;
- a shaft affixed to the support tower;
- a wind wheel mounted on the shaft in a manner that allows the wind wheel to rotate around its axis, said wind wheel comprising:
- a plurality of longitudinal spokes mounted on the rotor, each spoke having a tip;
- a semi-flexible wing attached to each spoke in a way that enables the angle of attack between the wing and the direction of the wind to be changed;
- a ring attached to the tip of each spoke;
- a fairing on the upwind side of the wind wheel that keeps the wind wheel on the downwind side of the support tower regardless of wind direction;
- one or more energy generators mechanically coupled to the ring;
- a controller that controls the angle of attack of the wings, the rotational resistance of the generators, and the energy produced by the generators in response to the wind speed.
