Wind power system has blades pivotably mounted on cantilevers so that, in rotation region with blades moving against wind, blades are moved by wind into position with minimal resistance to wind

摘要

The system has a main shaft (1) for turning blades (4) mounted on the shaft via cantilevers (3) protruding from the shaft. The blades are pivotably mounted on the cantilevers so that in a rotation region (A) in which the blades move with the wind they oppose the wind direction, and in a region (B) in which they move against the wind, the blades are moved by the wind into a position in which they have minimal resistance to the wind.
