WIND TURBINE Russian patent published in 2018 - IPC F03D3/04 F03D3/06 F03D7/06 

FIELD: wind power engineering.

SUBSTANCE: invention relates to wind power engineering. Wind turbine comprising a rotor mounted rotatably about a vertical axis, rotatable rigid blades fixed to the rotor asymmetrically relative to their rotation axes. At the lower ends of the runaway sections of the rotary rigid blades, additional vertical axes with freely rotating rollers are installed, rolling around the restrictive arc-shaped supports fixedly mounted on the lower base of the rotary body made in the form of a thin-walled cylinder partially enclosing the rotor, with rectangular symmetrical inlet and outlet openings on a cylindrical surface, with the radius of one arcuate support being less than the radius of the rotor, and the radius of the other arcuate support is greater than the radius of the rotor, a confuser is rigidly mounted on the inlet side, a weather vane is rigidly connected from the outlet to the body, and a pipe rigidly connected to the bottom base of the housing coaxially with the axis of the rotor, supported with rotation on the wind turbine bed.

EFFECT: invention is directed to increasing of the efficiency.
