发明名称 A METHOD OF MANUFACTURING A SPAR FOR A WIND TURBINE FROM ELEMENTS HAVING GEOMETRICALLY WELL-DEFINED JOINT SURFACE PORTIONS, AND THE RELATED SPAR
摘要 The invention provides a method of manufacturing a spar (1) for a wind turbine blade steps of providing at least two caps (2a, 2b), each cap forming an intermediate portion (4) between two end portions (5), where the end portions each forms a cap joint surface portion (6) along a longitudinal extending edge of the end portion and the intermediate portion forms an outer surface portion (7) of the spar, providing at least two webs (3a, 3b), each web being provided with web joint surface portions (8) along opposite and longitudinally extending edges, and connecting the joint surface portions of the caps with the joint surface portions of the webs to form a tubular configuration of the spar. The at least two caps are configured for attachment to a blade shell so that the intermediate portion of one of the caps faces towards or forms part of a windward surface of the blade and the other one of the caps faces towards or forms part of a leeward surface of the blade.
