Abstract
The following specification discloses an improvement in vertical axis wind machines having upstanding blades. The blades are attached to a rotatable ring which support the blades at an angle of forty five degrees to the horizontal plane of the ring. Associated with the wind machine is a wind velocity sensing device producing electrical signals responsive to the wind velocity. Means is provided the blades attached to the ring to adjust the angle of attack of the blades in response to the magnitude of the signals.
Claims1
In a vertical axis wind machine having a plurality of upstanding airodynamic blades the combination comprising;
- a rotatable ring pivotably supporting said blades;
- a wind velocity sensing device adapted to produce an electrical signal responsive to wind velocity;
- means for pivotably adjusting the angle of attack of said blades responsive to said signal;
- and wherein said ring rides on wheels disposed on a circular track and mounted on pillars, said ring composing a frame for a ring shaped armature on which permanent magnets of alternate polarity are mounted to form an electromagnetic energy converter, said armature having a plurality of pick-off stator modules mounted adjacent thereto to allow transfer of the electro induction current direct to cable means at ground level;
- said guide wheels having shafts to provide coupling to mechanical energy converting means.
