    Abstract: A method of manufacturing a wind turbine blade is described, the blade being formed from at least a pair of blade shells being joined together. For at least a portion of the wind turbine blade, the blade shells are joined by an overlamination applied between the edges of the blade shells, thereby substantially reducing or eliminating the need for a structural adhesive to join the blade shells, particularly in the area of the leading edge of the blade or the root region of the blade trailing edge. The overlamination can be formed from the same material as the blade shells themselves, thereby minimising the possibility of structural faults or cracks due to differences in materials or stiffness levels at the interface between the blade shells.

    Abstract: A wind turbine blade assembly comprising a wind turbine blade having a tip end and a root end, and a leading edge and a trailing edge with a chord length extending therebetween is described. The wind turbine blade assembly further comprises an aeroshell extender piece comprising a body for attachment to a trailing edge side of a profile of a wind turbine blade, the body having a first end for attachment to the trailing edge side of the profile, and a second trailing edge end to form an extended airfoil trailing edge profile for a portion of the profile of the wind turbine blade. The aeroshell extender piece is attached to the wind turbine blade at least partly using at least one profile wedge, said at least one profile wedge being shaped to compensate for the geometry of the wind turbine blade.

    Abstract: A wind turbine blade is provided with two shell parts each at least partly made of a sandwich structure including an inner skin (76), an outer skin (74), and an intermediate core material (75, 77), wherein the shell parts are bonded together at least along their respective leading edges (18). The blade also comprises a longitudinally extending spacing section in which the respective trailing edges (58a, 58b) of the pressure side shell part and the suction side shell part are spaced apart, wherein a trailing edge shear web (45) is arranged between and connected to the sandwich structure of the suction side shell part (84, 86, 87) and the sandwich structure of the pressure side shell part (74, 76, 77).

    Abstract: A wind turbine blade and an associated method of manufacture is described, wherein a structural bond line of the blade is positioned to be adjacent to a sandwich panel construction of the blade. By locating the structural bond line nest to a sandwich region of the blade, the buckling strength of the joint is improved and the risk of crack initiation in the adhesive joint is reduced considerably. This allows for a reduction in the amount of structural adhesive used in the blade, and/or a reduction in the amount of core material which is required in the sandwich panel to maintain the required blade stiffness. A particular advantage is provided in the region of the trailing edge of the blade, wherein the relocated structural joint considerably reduces the risk of buckling in the trailing edge side of the blade.
