Abstract
We conducted on numerical analysis on hydrodynamic and material solutions of a small type wind turbine with about 1.5-2 m diameter of wind receiving area having maple seed type blades made from CFRP. 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. Since the wind power as renewable energy has been come into the limelight by global warming and energy problems, small type wind turbine has been settled in general home and company. However, the widely used wind turbine blades are ordinary propeller type, and there is more complicated technique at the field of producing the blades. We used maple seed type blades made from CFRP because we kept the blades strength by becoming larger diameter of wind receiving area. We obtained the numerical results of Von Misses stress and displacement in the blade on the basis of the results from CFD around the blades. Finally, we investigated the power of the wind turbine in a large wind tunnel.
