Abstract: There is disclosed a method of balancing a set of first and second modular blade sections for a set of blades of a rotor of a wind turbine. The method comprises determining a mass moment of the first and second blade sections, the mass moment being deter-mined about an axis equivalent to an axis of rotation of a hub of the turbine when the blade section is assembled onto the hub. A plurality of blade section groups 10 are defined, each comprising a first blade section of the set and at least one second blade section of the set, each blade section group having a blade section group mass moment about the axis. The first blade section and the at least one second blade section in each group are selected so as to satisfy a minimised total ballast condition, to minimise balancing ballast to be added to the set as a whole, or a minimised 15 ballasting difference condition, to minimise the difference in balancing ballast added to different blades, or both.

Abstract: A method of making a wind turbine blade is described. The blade comprises an outer shell having a laminate structure. The method comprises providing a blade mould (82) defining a shape of at least part of the outer shell of the blade. The mould extends in a spanwise direction between a root end (94) and a tip end (96), and extends in a chordwise direction between a leading edge (90) and a trailing edge (92). The method further includes providing a plurality of dry plies (66) comprising dry structural fibrous material and a plurality of prepreg (68) plies comprising structural fibrous material impregnated with resin. The plurality of dry plies and the plurality of prepreg plies are arranged in the mould to form a plurality of layers of the laminate structure of the outer shell of the blade. The plies are arranged in the mould such that the dry plies are interleaved with the prepreg plies to form a hybrid shell structure in which the plies are arranged in a staggered relationship such that corresponding edges of the dry plies are offset from one another in the spanwise and/or chordwise direction of the mould and/or corresponding edges of the prepreg plies are offset from one another in the spanwise and/or chordwise direction of the mould.

Abstract: A hub for a wind turbine and a method for fabricating the hub are disclosed. The hub comprises a continuous shell forming a hollow body with a main shaft flange adapted to connect the hub to a main shaft, and one or more blade flanges, each blade flange being adapted to connect the hub to a wind turbine blade. The hub further comprises at least two hub parts, each hub part being casted separately from a castable material, and each hub part being subsequently connected to at least one other hub part via one or more connecting portions, so that at least one blade flange and/or the main shaft flange comprises a section forming part of or being attached to one of the hub parts and a section forming part of or being attached to another hub part, thereby ensuring that the casted parts have a size and a weight which are manageable during the manufacture, in particular during the casting. The hub may comprise one or more reinforcement elements arranged at or near the blade flange(s), e.g., comprising an inner wall arranged at a distance to the continuous shell, thereby forming a cavity between the inner wall and the continuous shell. This allows the regions between the blade flanges to be small or narrow, thereby reducing the size and weight of the hub, while maintaining a sufficient strength and stiffness of these regions.

Abstract: An aspect of the invention involves a method of transporting a blade for a wind turbine generator, the method comprising attaching a blade root support frame to a root flange of the blade and attaching a blade spanwise support frame to a spanwise portion of the blade as well as connecting a first wheel base to the spanwise support frame, and connecting a transport unit to the root support frame, where the transport unit includes a carrying structure and a second wheel base with at least one axle and two wheels, and where the transport unit before being connected to the root support frame, is moved into a position partly underneath the blade root, and where the second wheel base is underneath the blade and the carrying structure is underneath the root support frame. As the transport unit is moved into a position underneath the blade, such that the second wheel base is underneath the blade and the carrying structure is underneath the root support frame, the load from the root end of the blade is distributed between a truck or tractor, which is used for the transport, and the second wheel base, which lowers the axle pressure of the truck or tractor. Moreover, as the carrying structure is underneath the root support frame, only vertical load may be applied from the transport unit, such that forces and torque applied on the blade are substantially decreased compared to the known art. A second aspect involves that blades may be stacked by use of the support frames without use of further equipment.

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.
