Abstract: A wind turbine blade includes a first blade portion and a second blade portion coupled together by a connection joint. A first spar cap is associated with an upper shell half and a second spar cap is associated with the lower shell half of each of the first and second blade portions. A shear web extends between the first spar cap and the second spar cap of each of the first and second blade portions. The shear web is terminated away from a joint interface at which the first and second blade portions meet, and there is no shear web extending in a longitudinal direction across the joint interface. The shear web extending between the first spar cap and the second spar cap is branched in the longitudinal direction toward the first and second blade interfaces of the first and second blade portions respectively.

Abstract: A connecting joint for attaching a wind turbine rotor blade to a rotor hub includes a bolt having a blade end configured to be coupled to the rotor blade and a hub end configured to be coupled to the rotor hub. The bolt includes a neck region adjacent the blade end, wherein the neck region has a cross dimension less than a cross dimension of the blade end of the bolt. A wind turbine blade having such a connecting joint is also disclosed. Additionally, a method of making the connecting joint is disclosed.

Abstract: A shear web for a wind turbine blade is described. The shear web comprises a panel and a web head. A longitudinal edge of the panel is received within a slot defined in the web head. A plurality of discrete spring features are attached to the longitudinal edge of the panel. The spring features are mutually spaced apart at intervals along the length of the longitudinal edge. The spring features compress against a base of the slot when the longitudinal edge region of the panel is inserted into the slot.

Abstract: The present invention relates to a method of manufacturing a wind turbine blade or a part of a wind turbine blade. The method comprises arranging at least one of layer of uncured resin pre-impregnated fibres, called prepregs, and at least one layer of cured fibre reinforced resin in an at least partly overlaying relationship, and curing the resin of the at least one layer comprising uncured resin. The at least one layer of cured fibre reinforced resin is assembled with at least one layer of uncured resin-preimpregnated fibres prior to being placed on a moulding surface. The method may e.g. be used to manufacture a wind turbine blade shell member or a wind turbine blade spar member. The invention further relates to a wind turbine blade shell member or a wind turbine blade spar member manufactured by such a method. The invention further relates to a pre-form for use in a wind turbine blade, the pre-form comprising at least one of layer of uncured resin pre-impregnated fibres and at least one layer of cured fibre reinforced resin in an at least partly overlaying relationship.

Abstract: A wind turbine rotor blade includes an elongate body having a root end configured to be coupled to a rotor hub of a wind turbine. The rotor blade further includes a connection joint at the root end for connecting the rotor blade to the rotor hub. The connection joint includes a plurality of connecting elements integrated into the root end of the rotor blade and including an eye that defines a bore through the root end of the rotor blade. The connecting elements may be formed from folded fiber rovings wherein the fold forms the eye. A method of making a rotor blade having the connecting element integrated therein, and a method of making the connecting elements are also disclosed.

Abstract: The invention provides a method of providing a tapered edge on a sheet comprising a fibrous material, comprising moving the sheet while carrying out the following steps: —moving the sheet past a freezing device, which sheet is provided with a substance embedding the fibrous material, at least at a first edge of the sheet, which substance is in a non-solid state at room temperature, in particular at 20 degrees Celsius, and cooling the first edge using the freezing device, so that the substance at the first edge becomes solid, —moving the sheet past a machining device while the substance is solid from the cooling using the freezing device, and —machining, during the step of moving the sheet past a machining device, the first edge with the machining device to provide a first tapered edge.
