WIND TURBINE Russian patent published in 2010 - IPC F03D3/06 

FIELD: power industry.

SUBSTANCE: fluid medium turbine includes rotor and blade assembly which consists of rotor made with possibility of being rotated about rotation axis, and a lot of blades, each of which protrudes beyond external rotor surface. Each blade has an end and the main drive surface; at that, blades are made and located so that there is no effective open area between adjacent blades; at that, each blade is located within external thirty percents of the radius passing from axis centre to blade end. Turbine also includes stationary front part protruding in front of rotor and ensuring change of direction and increase of speed of coming fluid medium; at that, stationary front part has a shape and location in relation to blades, which provides direction of fluid medium towards the main drive surface of the blades. Stationary front part has at least partially spherical shape. A row of thin aerodynamic dividers is radially and uniformly arranged on the above spherical stationary front part and is meant for directing wind to short turbine blades.

EFFECT: increasing generation efficiency of useful energy at low flow velocities.
