A wind-driven power plant has a mast, windmill with horizontal axis of shaft, two-element concentrator with external as ring and internal as object with streamlined form directed along axis of the windmill shaft, a device for performing useful work placed in the inner element of concentrator. The ends of the blades of the windmill have streamlined form in two directions simultaneously – along flow and in direction of motion of those at their rotation with respect to axis of the windmill shaft, with placement in concentrator at place of maximal flow narrowing where inner element of the concentrator in plane normal to the shaft axis has interruption that divides the element into two parts – front one that covers the blades from flow, except of the ends of those, with formation together with the outer element of the concentrator of gradual narrowing of flow, and back one that serves for implementation of smooth flow takeoff from wind-driven power plant. |
