WIND-DRIVEN PLANT Russian patent published in 2011 - IPC F03D9/00 F03D1/02 

FIELD: power engineering.

SUBSTANCE: wind-driven plant comprises a shaft with a bearing and a cylindrical metal casing, the main and additional power generators and fin assemblies. The casing in the front has a socket, and at the back, via a flange, a cartridge, where an additional generator is installed with an impeller. The main generator is installed inside the casing and has a movable stator and a rotor made in the form of drums, which, through L-shaped spikes at their ends, are fixed in radial-axial bearings installed on a fixed stem. The fin assembly frame is made of metal pipes and is attached to the cartridge from the outside. A piezoelectric film is fixed on the frame, being pneumatically connected via exhaust holes in the cartridge bottom with the air flow that exits the plant.

EFFECT: increased capacity and efficiency of wind energy use and improved reliability.
