<P>PROBLEM TO BE SOLVED: To provide a wind turbine rotor blade improving buckling strength against a load in the edge direction, increasing the safety factor of the buckling strength close to the safety factor of material strength and further reducing the weight. <P>SOLUTION: The wind turbine rotor blade 5 includes an outer skin 11 formed of a fiber reinforced plastic, beams, and a trailing edge reinforcing member 20 forming a trailing edge part. The trailing edge reinforcing member 20 includes first recesses 21 containing the trailing edge-side ends of the outer skin material 11, and second recesses 22 containing the trailing edge sides of overlays 19. Third recesses 24 containing the front edge sides of the overlays 19 are formed at the trailing edge-side tips of the outer skin 11. The distal ends of the outer skin 11 are fixed to the first recesses 21 via an adhesive agent 23. <P>COPYRIGHT: (C)2011,JPO&INPIT |
