| 摘要 |
The present invention relates to wind turbines and more particularly to such a device having a horizontally disposed power output shaft pivotally supported by a turntable. Attached to the output shaft are a number of circumferentially spaced apart blades which are each hinged along their leading edges with the hinge axes inclined obliquely to the longitudinal axis of the shaft. A spring controlled governor is provided to control the pivotal position of each of the blades around their respective hinge axis of rotation.
