Abstract: A wind turbine blade and method of manufacture, the blade extending between root and tip ends on a longitudinal axis and having root, transition, and airfoil regions. The blade has a profiled contour with a chord extending between the leading and trailing edges; a blade shell with a first blade shell part with a pressure side and a second blade shell part with a suction side, the blade shell parts extending between root and tip ends and are joined on a primary glue joint; first and second main spar caps integrated in the first and the second blade shell parts, respectively, and have one or more shear webs there between. A third blade shell part may be present and joined to the first blade shell part along a first secondary glue joint and to the second blade shell part along a second secondary glue joint.
Abstract: A blade shell part for a wind turbine blade and a wind turbine blade are disclosed. The blade shell part is made of a composite structure comprising a reinforcement material embedded in a polymer matrix, the blade shell part extending from a tip end to a root end, wherein the blade shell part comprises: a blade shell body with a leading edge and a trailing edge, and a first glue flange extending from the leading edge and having a first glue flange edge and a first glue surface with a first width, wherein the first glue flange is provided with one or more spacer elements. Further, a method of manufacturing a wind turbine blade is described.
Abstract: The present invention relates to a transportation and storage system for a wind turbine blade (10), the system comprising a root frame assembly and a tip frame assembly. The frame assemblies comprise lateral frame parts (72, 74) each having a top member (84), a bottom member (86), a center beam (88), a first and a second upper inclined beam (90, 92) and a first and a second lower inclined beam (94, 96). The present invention also relates to the use of the system for transporting and/or storing one or more wind turbine blades.
