AbstractIn this study, the AIR-X 400-W wind turbine is modeled. The solid model of turbine components were generated by using ANSYS 13.0 software. Contrary to materials used in classical turbines, shape-memory alloys were preferred at blade root connections and rotor hub. Structural analyzes confirmed that the weak regions are screw connection points. In the created scenarios for turbine we obtained that turbine was more durable and has longer life than the 4140 structural steel when Ni-Ti was used in blade root connection and Cu-Zn-Al was used in rotor hub. Also Ni-Ti and Cu-Zn-Al combination was determined as approximately 2.1556 times longer life than 4140 structural steel.
