<P>PROBLEM TO BE SOLVED: To provide a wind turbine blade which is structured to prevent buckling without adding a large weight thereto, in order to prevent deformation or breakage due to the buckling of the wind turbine blade when a wind turbine for wind power generation is enlarged. <P>SOLUTION: The flexural rigidity in a blade thickness direction is monotonously decreased when a distribution is formed from a root of a blade to a forefront thereof, thereby attaining the wind turbine blade structured to prevent local buckling. <P>COPYRIGHT: (C)2013,JPO&INPIT |
