ROTOR BLADE FOR WIND TURBINE
FIG5 is a perspective view of a section of the blade in FIG2
According to another embodiment, sections of the blade 104 are pre-assembled and transported in the pre-assembled state. Then, the sections of the blade 104 may be attached to each other at the site for final assembly of the blade 104. A section 200 may be formed as illustrated in FIG5. The section 200 comprises a first connector 110a and a second connector 110b, the first and second connectors 110a, 110b being adjacent connectors in the blade 104. The section 200 further comprises the longitudinal strut members 108 and the diagonal strut members 112 between the connectors 110a, 110b. Hence, the longitudinal strut members 108 and the diagonal strut members 112 are mounted to the connectors 110 before transport to the site. At the site, sections 200 may be attached to each other for final assembly of the blade 104.

['1. A blade for a rotor of a wind turbine, said blade (104) comprising a plurality of interconnected blade sections, each blade section comprising: a truss-like three-dimensional structure comprising a plurality of longitudinal strut members (108) extending substantially along the longitudinal direction of the blade (104), at least two connectors (110) extending in a cross-sectional direction of the blade (104), and diagonal strut members (112) extending diagonally through the blade (104) between two of the at least two connectors (112), thereby forming the truss-like three-dimensional structure, wherein the plurality of longitudinal strut members (108) are separated along an entire longitudinal direction of the blade (104), wherein the at least two connectors (110) are connected to the plurality of longitudinal strut members (108), and wherein the plurality of blade sections are interconnected by means of a connector of a first section being attached to a connector of a second section.']
