  • Patent number: 11002247
    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.
