The project designed several types of VAWT blades with the goal of maximizing the efficiency of a Savonius turbine. This drag-type VAWT turns relatively slowly, but yields a high torque.. This wind turbine blade is used to modeling the vertical axis wind turbine rotors. The straight three bladed vertical axis wind turbine rotor is twisted to 45degrees and 90 degrees in order to improve the performance of rotor. By twisting the rotor by maintain the height and diameter of rotors the weight of rotor are significantly increased to decrease the weight without compromising the performance of the rotor. For this purpose, the CAD modeling software Solid Works creates the aerofoil and the structural analysis in ANSYS of a straight and twisted three bladed vertical axis wind turbine rotor has been undertaken.
