Abstract: The disclosure relates to a section of a wind turbine rotor blade, the section comprising: three or more wing members extending along each other, at a distance from each other, and along a longitudinal direction of the wind turbine rotor blade, wherein at least one, and preferably each, wing member has an airfoil shaped cross-section as seen in a plane transverse to the longitudinal extension of the wing member, wherein each wing member extends from a respective inner end to a respective outer end, wherein the section further comprises a first plurality of three or more struts and a second plurality of three or more struts, wherein the struts in the first plurality of struts each extend from an inner end of one wing member to an inner end of another wing member, such that the struts in the first plurality of struts interconnect the wing members at their inner ends, and wherein the struts in the second plurality of struts each extend from an outer end of one wing member to an outer end of another wing member,

Abstract: A blade (104) for a rotor of a wind turbine is provided. The blade (104) comprises: a truss-like three-dimensional structure having strut members (108; 110; 112) forming the truss-like structure, wherein a plurality of the strut members (108; 110; 112) in the truss-like structure have an airfoil-shaped cross-section.

Abstract: 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 has an airfoil shaped cross-section as seen in a plane transverse to the longitudinal extension of the wing member, 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 an
