ABSTRACT:
To generate power from wind economically, a feathering vane is pivotally mounted perpendicular to a tail vane and shifts the orientation of a sprocket assembly controlled by the tail vane in response to wind velocity. The sprocket assembly changes the orientation of blades which orbit about and rotate the main power shaft so that, as wind velocity changes, the blade orientations are shifted in a compensating direction under the control of the tail vane. A lever shifts the position of the blades to positions that balance wind power and brake the rotation for maintenance purposes. The speed-control mechanism includes a damper to avoid being excessively affected by wind gusts. The main shaft is connected through a speed increaser which has less mass at the high-speed end than the low-speed end to an induction generator when used for cogeneration, the field of the induction generator being excited by the cogeneration frequency.
