摘要
The rotor extends from a leading end approached by the wind, to a trailing end. Its spacing from the axis (1) reduces continuously in this direction. The blade (6, 7) cross section slants rearwardly and towards the axis, at a 45[deg] -90[deg] degree angle, preferably at about 60[deg] . Blade width is constant over its length, or it tapers towards the rear. The asymmetrical blade profile includes curved and flat sides, the flat side being directed against the wind flow direction. The turbine is contained in a funnel-like wind interceptor.
