【Abstract】 In order to reduce the negative power conducted in the rotating process of resistance-type wind turbine,the principle and stucture of a kind of wind turbine with high efficiency is studied. In the wind trubine,the direction of turbine blade can be controlled by using mechanical transission devices and facing the wind against the wind. The wind turbine is simpler in structure,more reliable in performance and higher in efficiency than ordinary wind turbine.更多还原
