WIND TURBINE Russian patent published in 2014 - IPC F03D1/00 

FIELD: power engineering.

SUBSTANCE: this invention relates to the field of wind power engineering and may be used for production of electric energy. A wind turbine comprises a set of bent blades fixed on a central rotary hub and a rim surrounding the ends of the blades and fixed to them, at the same time the rim is made as capable of rotation together with the specified hub and the specified blades. Each blade has fixed inclination relative to the central axis of hub rotation. The angle of inclination of each blade in the hub end is determined by the result of the ratio produced, if the radius of the hub is divided by the turbine radius and is multiplied by the angle of inclination at the end, at the same time the blade comprises a complex curve, which causes deviation of wind dashing against the blade as the wind enters the area of the blade. The turbine additionally comprises a device, which controls speed of turbine rotation, so that it is possible to control angle of blades inclination relative to wind direction.

EFFECT: use of the invention provides for increased efficiency of wind energy use.
