Abstract: A hub (1) for a wind turbine is disclosed, the hub (1) comprising a continuous shell forming an internal space within a hollow body, and the hub (1) further comprising a main shaft flange (2) adapted to connect the hub (1) to a main shaft and one or more blade flanges (3), each blade flange (3) being adapted to connect the hub (1) to a wind turbine blade. The hub (1) comprises one or more reinforcement elements connected to the shell and extending from an inner surface of the shell and inwardly into the internal space within the hollow body. This allows the regions between the blade flanges (3) to be small or narrow, thereby reducing the size and weight of the hub (1), while maintaining a sufficient strength and stiffness of these regions.

Abstract: 5 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 determined 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.
