    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 wind turbine blade mould extending longitudinally in a spanwise direction and transversely in a chordwise direction is provided and a spar cap (134, 136) is laid the mould. The spar cap comprises a plurality of strips (138) extending longitudinally in the spanwise direction and arranged side-by-side in the chordwise direction, said strips comprising one or more intermediate strips (158) arranged between peripheral strips (160, 162) which are inclined relative to the intermediate strips. A shear web (126) comprising a flange (130a) extending longitudinally in the spanwise direction is provided, the flange comprising a base (144) defining a primary bonding surface (164). A chordwise width of the primary bonding surface corresponds substantially to a chordwise width of the intermediate strips of the spar cap. The primary bonding surface of the flange is bonded to the one or more intermediate strips of the spar cap.

    Abstract: A modular wind turbine blade is described. The modular blade comprises a first blade 5 module having a first spar cap extending longitudinally in a spanwise direction and a second blade module having a second spar cap extending longitudinally in the spanwise direction. The blade modules are configured for connection end-to-end via their respective spar caps. The first spar cap comprises first and second beams arranged side-by-side, each beam having a tapered end defining a scarfed surface. The tapered end of the first 10 beam extends beyond the tapered end of the second beam. The second spar cap comprises first and second beams arranged side-by-side, each beam having a tapered end defining a scarfed surface. The tapered end of the second beam extends beyond the tapered end of the first beam. The blade modules are configured such that when the modules are connected together the scarfed surfaces of the respective first beams mate 15 to form a first scarf joint and the scarfed surfaces of the respective second beams mate to form a second scarf joint. The first scarf joint is offset from the second scarf joint in the spanwise direction.

    Abstract: A method of making a wind turbine blade is described. The wind turbine blade comprises first and second half shells joined together and a shear web bonded between inner surfaces of the respective half shells. The blade is made in a one-stage join up process, which involves supporting the half shells in respective mould halves, and arranging one of the half shells on top of the other half shell with the shear web arranged between the two half shells. Adhesive is provided between the shear web and the inner surfaces of the respective half shells. During the join-up process, the shear web is supported by stabilisers. The use of stabilisers avoids the need for a jig to support the shear web. Stabilisers attached to an inboard end of the shear web may remain accessible after the join-up and can be removed.

    Abstract: A method of manufacturing a wind turbine blade using pre-fabricated stacks of reinforcing material is described. The stacks 14 comprise a plurality of plies of fibre material, joined together along a side edge to form a spine. The opposite edges of the stack are left unjoined so that the plies can separate and slide across one another. In doing so, the stacks can be stored flat, but on installation into a curved mould 12 profile, the plies may slide to adopt the curved shape of the mould. The stacks extend from a point near the leading or trailing edge of the mould to an intermediate point on the mould surface. The stacks may be used to construct the thickened root section of a wind turbine blade.
