摘要： A wind turbine rotor blade (5) is provided. The blade (5) comprises: a three-dimensional truss-like frame extending in a longitudinal direction of the rotor blade (5). The frame comprises a plurality of longitudinal frame members (9, 11, 13), an inner (27) and an outer (29) support, each being connected to the plurality of longitudinal frame members (9, 11, 13), a plurality of diagonal frame members (15, 17, 19, 21, 23, 25), extending between the inner (27) and the outer (29) support, wherein at least one (15, 17, 19, 21, 23, 25) of the diagonal frame members (15, 17, 19, 21, 23, 25) at one end is connected to the inner support (27) and at an opposite end is connected to the outer support (29), wherein said at least one diagonal frame member (15, 17, 19, 21, 23, 25) is pre-tensioned between the inner (27) and the outer (29) support by being subject to an internal force in the frame.

摘要： The disclosure relates to a rotor blade (104) for a wind turbine, the rotor blade (104) comprising two or more wing members (110, 112, 114), wherein each wing member (110, 112, 114) is divided into at least a first sub-member (110a) and a second sub-member (110b), the sub-members (110a-b) being arranged one after another along a longitudinal direction of the rotor blade (104), wherein, in each wing member (110, 112, 114), at an interface (116) between the first and the second sub-member (110a-b), the first sub-member (110a) is arranged in the rotor blade (104) with an outer end angular orientation about the longitudinal direction and the second sub-member (110b) is arranged in the rotor blade (104) with an inner end angular orientation about the longitudinal direction, the inner end angular orientation of the second sub-member (110b) being different from the outer end angular orientation of the first sub-member (110a). The disclosure also relates to a sub-member adapted to extend from an inner end to and outer end and to thereby form a discrete portion of a longitudinal extension of a wing member (110, 112, 114) of a rotor blade (104) for a wind turbine.
