FLUID MEDIUM TURBINE SYSTEM (VERSIONS) Russian patent published in 2015 - IPC F03D3/04 F03D7/06 F03D11/00 

FIELD: machine building.

SUBSTANCE: invention relates to fluid medium turbines on and, in particular, to fluid medium turbines with a vertical axis. The turbine (100) is a wind turbine with a vertical axis intended for generation of the electric power from the wind power. The system (100) has a vane unit (140). The unit (140) has vanes (142, 144, 146, 148), designed with a possibility of rotation around of the axis (Y). The system (100) has a concentrator (120), designed with a possibility of mounting windward and in front of return side of the unit (140). The concentrator (120) can form a convex surface facing windward. The system (100) has a regulated concentrator (110), designed with a possibility of positioning windward with reference to the pushing side of the unit (140). The concentrator (110) is designed with a possibility of switching between the first and the second position, and the concentrator (110) is capable to deflect more wind to the turbine (100) in the first position, than in the second position.

EFFECT: invention is aimed at efficiency improvement.
