Aerodynamic wind rotor with vertical axis with variable angle of attack

Abstract

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.
