Abstract:
A wind rotor comprising:a base, a rotor frame rotationally supported on the base for movement about a substantially vertical axis in one of a clockwise or counter clockwise direction, a plurality of wind receiving vanes pivotally disposed on the rotor frame for pivotal movement with respect to the rotor frame about a substantially vertical axis in a clockwise and counter clockwise direction between a first closed position and a second open position, the movement of the vanes from the first closed position to the second open position being the one of the clockwise and counter clockwise direction that corresponds to the direction of the rotational movement of the rotor frame, and a variable resistance damping mechanism assembly disposed between each vane and the rotor frame, the variable resistance damping mechanism assemblies being configured to provide damping in both the clockwise and the counterclockwise directions of the vanes pivotal movement with respect to the rotor frame, the variable resistance damping mechanism assembly further configured to dampen a greater amount in one of the clockwise or counterclockwise directions than in the other.
