The field of research refers to the creation of wind energy conversion devices, namely to the wind turbines with vertical axis.
The wind turbine with vertical axis includes a tower on which a rotary shaft with blades with an inclined aerodynamic profile is installed, the ends of which by means of V-class kinematic couplings are coupled with a rotary shaft connected to the permanent magnet generator. The V-class kinematic couplings have a common axis and ensure the variation of the angle of attack depending on the speed of the air flow in automatic mode.
