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: 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.
