We have clarified the power characteristics and the transient response of the power in a small type wind turbine at about 1.1 m diameter of wind receiving area having maple seed type blades in a great wind tunnel experimentally. We have proposed a new type of wind turbine blade having the possibility of easy producing the blades which are imitated the rotation of falling maple seed in the nature world. At the study, we used maple seed type blades made of CFRP because we kept the blades strength by becoming larger diameter of wind receiving area. In the present study, as a subsequent experiment, we conducted on the outdoor proof examination. By comparison of the accumulated power per day to the type of ordinal propeller wind turbine, we can obtain more power at the type of maple seed than that of propeller because that its transient response to the wind at the maple seed type blade is better than that at the ordinary propeller type blade.
