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: A wind turbine blade for a wind turbine includes an elongate body having a root end, a tip end, a leading edge, a trailing edge, a pressure side and a suction side, wherein the elongate body defines a longitudinal axis extending along a length of the elongate body from the root end to the tip end. The elongate body includes a pre-bend configured such that when the wind turbine blade is mounted on the wind turbine and orientated in an operative position, the blade generally curves in an upwind direction such that the tip end of the blade is positioned more upwind than the root end of the blade. The curve that defines the longitudinal axis of the elongate body has an inflection point between the root end and the tip end of the blade. A method of making such a wind turbine blade is also disclosed.
