Abstract

See full text

There is provided a wind turbine blade extending longitudinally in a spanwise direction between a root end and a tip end, and transversely in a chordwise direction between a leading edge and a trailing edge. The wind turbine blade comprises an outer shell defining a substantially hollow interior, and a shear web arranged inside the outer shell and extending longitudinally in the spanwise direction. The shear web comprises an elongate web panel and a mounting flange extending along a longitudinal edge of the web panel, the mounting flange comprising an inboard end portion defining a root end of the mounting flange and an outboard portion defining a tip end of the mounting flange. The outboard portion extends along a majority of the length of the elongate web panel. The inboard end portion of the mounting flange is bonded to an inner surface of the blade shell by a first adhesive, and the outboard portion of the mounting flange is bonded to the inner surface of the blade shell by a second adhesive. The first adhesive has a lower elastic modulus than the second adhesive, and/or a chordwise width of the inboard end portion of the mounting flange is enlarged in comparison to a chordwise width of the outboard portion of the mounting flange adjacent to the inboard end portion.
