AEROFOIL FOR VERTICAL SHAFT TYPE WIND POWER GENERATION DEVICE AND DESIGN METHOD FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an aerofoil for a vertical shaft type wind power generation device and a design method for the same capable of reducing air resistance during a rotation without deteriorating rotational efficiency. SOLUTION: In the vertical shaft type wind power generation device for generating electricity by rotating a vertical shaft type blade 3 attached on a rotating shaft connected to a generator about the rotating shaft by wind power, the horizontal section of the blade 3 has a curved asymmetrical shape having the maximum width of the horizontal section of the blade 3 same as the passing width Ps2 of a locus drawn when the horizontal section of the blade 3 is rotated about the rotating shaft.
