Abstract: The test was carried out on the FD-09 low speed wind tunnel of the Beijing Institute of Aerodynamics. When the wind speed in tunnel is 5.50 m/s, the output power of the concentrated wind energy turbine model is 100 W which is 3.8 times of the output power of the ordinary wind energy turbine with same diameter and 6 times of the output power of the small sized wind energy electric generator commonly used in the prairie in China at present. And its starting wind speed required is lower than that required for the ordinary wind energy turbine equipped with same blades.
