In this study, the influence of fluctuating flow on aerodynamic characteristics of airfoil for wind turbine was investigated experimentally by wind tunnel. The wind tunnel tests were conducted for the chord Reynolds number from 1.0×10^5 to 4.0 × 10^5, and the range of the attack angle between -10 degree to +28 degree. As a result, it is clear that fluctuating flow valid on repressing laminar layer separation at Re=1.0×10^5, α=+2〜+8(degree). In addition, fluctuating flow doesn't occur hysteresis and delay stall at Re=(1.0〜4.0)×10^5.
