This paper describes the performance of self-start for vertical axis wind turbine with variable-pitch straight blades . Our aim is to get basic data of performance characteristic of self-start for vertical axis wind turbine. The proposed variable-pitch angle mechanism has an eccentric point that is different from the rotational point. The main feature of the mechanism is to be able to change attack angles according to the rotational angles of the blades without actuators.We measured the performance of self-start for wind turbines of fixed straight blades and variable-pitch straight blades by using an open circuit type wind tunnel and CFD. It was found that the performance of self-start of the wind turbines is dependent on the angle of attachment and the angle of rotation. The static torque coefficient of the wind turbine with variable-pitch straight blades is larger than that of the wind turbine of fixed straight blades.
