The present study investigate the effect of angle change of the airfoil flap on the amount of power generation, and also examine the minimum starting velocity of the wind. The conclusion obtained are followings. The generated electric power using the flap wing is possible keep the optimal condition by changing the flap angle appropriately for high wind velocity. But it is better to keep low angle for low wind velocity. For wind velocity of 4〜14[m/s], the flap angle 25° is found to be best (optimized) value. Efficiency of power generation for flap wing without fixed angle (free condition) is almost same as that of the optimized value (25°)under fixed angle for condition.
