<P>PROBLEM TO BE SOLVED: To provide a wind turbine blade configured so that limitations in the manufacturing and transportation thereof are reduced, the weight thereof can be reduced, and a reduction in performance and an increase in noise can be reduced. <P>SOLUTION: This wind turbine blade 11 includes an outer skin 13 forming a long hollow space having a wing-shaped transverse cross-section, and a main beam 15 which is inserted in the longitudinal direction and reinforces the outer skin 13 from the inside. The blade root-side portion of the outer skin 13 is divided into an outer skin body 19 including a leading edge 17 and a divided outer skin 23 including a trailing edge 21 in the lateral direction. The divided outer skin 23 is attached to either the outer skin body 19 or the main beam 15 so as to be movable in the longitudinal direction relative to the outer skin body 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
