Description

At the present study, we 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 previous study, we dealt with the wind turbine at 0.13 m diameter of wind receiving area. At this case, we clarified the wind turbine has larger power experimentally. At this present, we used maple seed type blades made of CFRP because we kept the blades strength by becoming larger diameter of wind receiving area. We obtained its power and rotation from the wind turbine generator among experimental conditions of the blade installation angle and the blade rigidity. By comparison, they vary by the conditions, and there are the most suitable conditions. We also obtained the result that its transient response to the wind at the maple seed type blade is better than that at the ordinary propeller type blade.
