Wind powered turbine. |
摘要 |
<p>A wind powered turbine of the vertical axis type having rotor blades (3) carried on a rotor arm (2), in which the blades can be reefed to reduce torque on the turbine. The blades have two portions (6, 7) pivotable with respect to one another by the reefing means so as to move from a position parallel to the rotation axis to a position at which they form an angle about a plane perpendicular to the rotation axis.</p> |
