VERTICAL AXIS WIND TURBINE Russian patent published in 2018 - IPC F03D3/06 F03D3/02 F03D7/06 

FIELD: hydraulic machines and engines.

SUBSTANCE: invention relates to wind power engineering. A device for converting wind energy into mechanical or electrical energy comprises a base, a hollow mast mounted on the base along a vertical axis, at least one module having a general shape of a body of revolution about the axis coaxially arranged around the mast and being rotatable about said mast, wherein said module comprises at least one flap extending between an end connected by a pivot connection and a free end, wherein said flap is movable around the pivot connection between a retracted position and a deployed position, means for moving the flap between its deployed and retracted positions, depending on the angular position of said flap around the mast, wherein said means of movement can be disconnected, a shaft disposed in the hollow mast coaxially with the module, coupled in rotation with said module about said axis and interacts with the converter of the mechanical energy of rotation of the shaft into mechanical or electrical energy.

EFFECT: invention is aimed at increasing the efficiency of the device.
