    Abstract: A wind turbine blade has a first blade portion and a second blade portion, each blade portion having a spar cap portion. A connection joint for coupling the first and second blade portions together includes first layers associated with the first spar cap portion and second layers associated with the second spar cap portion. The first and second layers each have a cut out at one end and are interleaved with their cut outs aligned. Fasteners pass through the cut outs of the first and second layers and are tensioned to clamp together the interleaved layers between the first and second blade portions.

    Abstract: A composite material blank (190) comprising an elongate blank body (300) extending between a first end face (312a) and a second end face (312b); said blank body (300) extending in a longitudinal direction, parallel to a longitudinal axis thereof, and having four peripheral sides (341, 342, 343, 344); each said first and second end face (312a, 312b) having edges (361a-364a; 361b-364b) which define a trapezoid shape; wherein the peripheral sides (341, 342, 343, 344) of said blank body (190) connect the edges (361a-364a) of said first end face (312a) with the edges (361b-364b) of said second end face (312b); and wherein said first trapezoid end face (312a) is inverted in relation to said second trapezoid end face (312b). A method of manufacturing a composite blank (190), and a wind turbine blade root insert (105) which may be formed from a blank (190).

    Abstract: An insert (105) for a wind turbine blade root. The insert (105) has a bushing (40) and an outer surface with circumferential annular grooves (68). A transition layer 5 (102) is built up around the bushing (40). The transition layer (102) has fibrous material sheet layers and filamentary material windings (80) in the grooves which alternate with fibrous plies (98) covering the grooves (68). Each fibrous ply (98) is anchored into the grooves (68) by the windings (80). Fibrous battens (148) are fitted around the transition layer (102) to form an insert body (108). Each batten (148) 10 has a deltoid cross-section so that the battens give the insert a quadrilateral or trapezoidal cross-section.

    Abstract: A blade handling system and method for conducting tomography (x-ray) scans of wind turbine blades to detect various types of manufacturing defects before blade installation are provided. The blade handling system includes support trollies, at least one of which is partially formed from low density materials that do not absorb X-rays, at least in the portions that directly contact the blade or are adjacent to the blade. The blade handling system engages the blade with a rigid support arrangement that immobilizes the blade against vibrations such that the blade can be moved past a tomography scanner and an accurate X-ray scan can be taken of the blade, unaffected by the support trollies. Longitudinal scans and detailed re-scans of certain cross sections using CT scanning by the tomography scanner are used to detect and diagnose many different types of manufacturing defects.
