WIND TURBINE BASED ON SAVONIUS ROTOR (OPTIONS) Russian patent published in 2021 - IPC F03D3/06 F03D13/20 

FIELD: wind energy.

SUBSTANCE: inventions group relates to wind energy, in particular to wind turbines with a vertical axis of rotation based on the Savonius rotor. The wind turbine contains at least three blades fixed on a vertical shaft, having a cut at an angle to the axis of rotation. The wind turbine contains a frame of strapping rails laid in a horizontal plane, connecting the blades in pairs at the attachment points farthest from the axis of rotation. Each strapping bar is fastened to a blade at the place of the horizontal through passage through this blade. The frame contains radial rails connecting the strapping rails to the vertical shaft.

EFFECT: uniform distribution of the wind load on all turbine blades, removal of some of the forces from the most vulnerable points of attachment of the blades to the shaft, a significant reduction in the twisting deformations of the blade.
