WIND-DRIVEN POWER PLANT Russian patent published in 2013 - IPC F03D7/06 

FIELD: engines and pumps.

SUBSTANCE: wind-driven power plant comprises a tower, a rotary base, rotary shafts with blades, stator elements, rotor elements, a weather vane with a wind direction sensor. Between rotor elements and shafts of the blades there are position fixators installed with spring elements. Fixators are made in the form of a self-breaking reduction gear or a core with a coil. Wind force is perceived with blades arranged on rotary rotors and rotary base, which jointly with rotor elements rotate, passing via stator elements fixed on the tower base. A magnetic circuit is closed, and blades rotate to 90°, after signal realisation the position of the blades is fixed. The weather vane rotating via the wind direction sensor sends a signal to stator elements, thus correcting time of blades rotation.

EFFECT: increased efficiency of a plant due to optimal orientation of blades relative to a wind flow.
