| 摘要 |
The invention relates to a wind driven turbine, which includes a rotor comprising a plurality of spaced apart vanes. The rotor is adapted to rotate about the vertical axis of an elongate short which can transmit power to a prime mover or power take off. Each vane for the rotor is formed with a substantially concave, elongate trailing or reverse face. Wind deflection means are provided, such as to direct wind, through a venturi, onto and along the concave trailing face of one or more vanes, as said one more vanes rotate downwind away from said venturi. The wind deflection means can also assist in at least partially shielding from the wind, one or more vanes of the rotor, as the vanes rotate and move upwind towards the venturi. |
