REINFORCED BLADE FOR WIND TURBINE

摘要

Wind turbine blade (20) with reinforcement of a box girder (21) for inhibiting transverse shear distortion of the blade. Reinforcement can be achieved either by a straight member (24) connecting diagonally opposed corners inside the girder that can be x-shaped, or by an angle bar (100) with legs (102, 104, 108) abutting the girder and the upper and/or lower parts of the blade shell (25,26). Reinforcing members can extend spanwise along the blade length.
