WIND-DRIVEN POWER PLANT Russian patent published in 2015 - IPC F03D1/00 

FIELD: power industry.

SUBSTANCE: wind-driven power plant has hollow blades fixed on its hub, which are made in the form of rotation bodies with longitudinal slots made in their walls, in which there arranged are convergent curved channels with tangential slots at the outlet, which are directed at a tangent to the outer surface of the blades. Air supply to tangential slots on the blades is provided by means of a compressor. The compressor includes an impeller driven from a device with an adjustable rotation speed, which is fixed on the shaft cantilever. At rotation of the compressor impeller, compressed air is supplied to tangential slots and ejected from them in the form of near-wall high-speed jets. As a result, a ring-shaped vortex is formed around the blades, at interaction of which a torque moment is created with an incident air flow on a windwheel.

EFFECT: increasing wind energy use coefficient and decreasing aerodynamic noise at operation of a wind-driven power plant in a wide range of wind speed variation at constant rotation speed of a windwheel and an electric generator.
