Abstract

Vertical wind turbine with two rotors a common vertical axis of rotation (1) around which two rotors are rotating, in the process of which one rotor is set inside the other. An internal rotor (2) has specially- designed blades (21) that rotate only in one direction. An external rotor (3) can rotate in the same or the opposite direction of the internal rotor (2). The direction of rotation depends to the shape of the inlet guide vanes (20). The inlet guide vanes (20) are arranged to reduce the impact of harmful torque to a minimum, which increases the efficiency of the kinetic wind energy. The central supporting structure (8) is located within the internal rotor (2). Both rotors lean on the central supporting structure (8).
