VERTICAL AXIS TYPE WIND POWER GENERATOR FUSED LIFT AND DRAG

摘要

PURPOSE: A vertical-axis wind turbine using the fusion of lift and drag is provided to improve the efficiency of generating power from a drag blade as wind flow energy is effectively converted into rotary force according to a revolution position. CONSTITUTION: A vertical-axis wind turbine using the fusion of lift and drag comprises a rotary shaft(10), upper and lower support bars(20), drag blades(30), lift blades(40), a generator gear box(60), and a tower(70). The upper and lower support bars are extended toward the outside from the rotary shaft. The drag blades are vertically placed between the upper and lower support bars. The center of the drag blade is connected to the end of the support bar, and rotates around the center of the rotary shaft. The lift blades are horizontally extended from the end of the support bar, and rotate around the rotary shaft. The generator gear box produces electricity using rotary force generated by the lift and drag blades. The tower supports a rotor which is connected to the rotary shaft, support bars, drag and lift blades.
