Wind power generation has a potential as an environmental friendly energy. Small wind turbines have attracted attention for installation as an effective utilization for natural energy and emergency power supply. Our research has been focused on the compact Darrieus type (straight bladed Gyro-mill type) vertical axis wind turbine using elastic wings on morphing technology. Three different types of materials, PET (Poly-Ethylene Terephthalate), aluminum plate and stainless steel plate were used for auxiliary wings. The maximum tip speed was obtained in the case of aluminum plate at 1.0 mm plate thickness. As a result of the performance experiment with loading, the unique phenomenon is observed by the auxiliary wing deformation. The unique fluid motion can be discussed by analyzing image tracking.
