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 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.

Abstract: The invention provides a method of inspecting a wind turbine blade. The method includes providing a defect inspection tool having an array of pins, the pins being displaceable in an axial direction relative to one another. The method includes positioning the defect inspection tool against a defect on the wind turbine blade to cause displacement of at least some of the pins in the axial direction, the displaced pins describing a contour representative of a contour of the defect. The method includes determining dimensions f the defect by inspecting the contour described by the displaced pins. Advantageously, the invention provides for a more accurate determination as to whether a defect needs to be repaired.

Abstract: In a first aspect of the invention there is provided a wind turbine blade shear web comprising an elongate web panel and a mounting flange extending along a longitudinal edge of the panel. The mounting flange comprises a base for bonding the shear web to a surface of a wind turbine blade shell and an upstand extending transversely to the base. The upstand is adhesively bonded to a side surface of the web panel and inclined relative to the side surface such that a bond gap is defined between the upstand and the side surface. The bond gap is at least partially filled with adhesive and one or more spacers are located in the bond gap, wherein the one or more spacers are configured to set an angle of inclination between the panel and the base of the mounting flange.

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 method of making an elongate reinforcing structure, such as a shear web, for a wind turbine blade is described. The reinforcing structure comprises a longitudinally-extending web and a longitudinally-extending flange. The flange extends along a longitudinal edge of the web and is arranged transversely to the web. The method involves providing a flange structure comprising a flange portion, and a projecting portion that extends along the length of the flange portion and projects transversely from a surface of the flange portion. The projecting portion is bonded between laminate layers of the web. The flange structure is preferably a pultruded component having a T-shaped cross-section. The method allows a simple, inexpensive and reconfigurable mould tool to be used. In preferred embodiments the mould tool has a flat surface without sidewalls.

Abstract: According to the present invention there is provided a mould for making a wind turbine blade shear web. The shear web comprises a longitudinally-extending web panel and a mounting flange extending along a longitudinal edge of the web panel and transverse to the web panel. The mounting flange comprises a first portion extending on a first side of the web panel and a second portion extending on a second side of the web panel. The mould comprises a longitudinally-extending main surface shaped to form the web panel, the main surface having a longitudinal edge. The mould further comprises a side surface arranged transverse to the main surface and extending downwards from the longitudinal edge of the main surface. The mould further comprises a base surface arranged transverse to the main surface and spaced from the side surface, the base surface having a first portion extending below the main surface to a first end of the base surface and a second portion extending above the main surface to a second end of the base surface. The first portion of the base surface is spaced from the side surface to define a mould cavity between the side surface and the first portion of the base surface, the mould cavity being configured to form the first portion of the mounting flange. The mould further comprises a datum-forming surface extending transversely from the second end of the base surface and defining a longitudinal edge at an intersection of the second portion of the base surface and the datum-forming surface. The second portion of the base surface and the datum-forming surface are configured to form the second portion of the mounting flange, and the datum-forming surface is configured to define a longitudinal edge of the second portion of the mounting flange.

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 (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) has a deltoid cross-section so that the battens give the insert a quadrilateral or trapezoidal cross-section.
