    Abstract: Improvements relating to wind turbine blade manufacture A method of making wind turbine blades of variable length is described. The method involves forming first and second half shells of a main blade section in a main blade mould assembly. A pre-manufactured tip section is selected from a plurality of tip sections of different lengths according to a total length requirement for the wind turbine blade. The tip section is supported adjacent to the main blade mould assembly such that an inboard end of the tip section overlaps with an outboard end of one of the half shells of the main blade section. The main mould assembly is then closed to bond the two main half shells together and to bond the tip section to the main blade half shells. The invention allows blades of different overall length to be produced using a common main blade mould assembly.

    Abstract: An insert (105) for a wind turbine blade root. The insert (105) has a bushing (40) and an outer surface with circumferential annular grooves (68). A transition layer 5 (102) is built up around the bushing (40). The transition layer (102) has fibrous material sheet layers and filamentary material windings (80) in the grooves which alternate with fibrous plies (98) covering the grooves (68). Each fibrous ply (98) is anchored into the grooves (68) by the windings (80). Fibrous battens (148) are fitted around the transition layer (102) to form an insert body (108). Each batten (148) 10 has a deltoid cross-section so that the battens give the insert a quadrilateral or trapezoidal cross-section.

    Abstract: A modular wind turbine blade is described. The modular wind turbine blade comprises first and second blade modules each comprising a proximal end and a distal end, a first side comprising a first aerodynamic surface being a windward surface or a leeward surface, a second side comprising a second aerodynamic surface being the other of the windward surface or the leeward surface, and a tapered end portion having a thickness between the first and second sides that decreases towards an end of the. The tapered end of the first blade module has a thickness that decreases towards the distal end, and that defines a mating surface on the second side of the module that extends between the distal end and the second aerodynamic surface. The second blade module has a tapered end portion having a thickness that decreases towards the proximal end, and that defines a mating surface on the first side of the module that extends between the proximal end and the first aerodynamic surface. The mating surfaces of the first and second blade modules are configured to form a scarf joint between the first and second blade modules. The invention also provides a mould assembly for making the blade modules, and a method of assembling the modules.

    Abstract: 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 5 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 10 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 15 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.
