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 wind turbine blade portion connector is configured to attach a first blade portion to a second blade portion of a wind turbine blade. The connector comprises a double-ended threaded stud bolt and a spring. The bolt has two threaded portions with opposing threads configured to be threadedly engaged with respective threaded holes of the first blade portion and the second blade portion. The bolt also has a tool engagement feature fixed in rotation with and disposed between the two threaded portions for rotating the bolt, and a bearing surface disposed between the two threaded portions. The spring is configured to bear against the bearing surface and exert a tensile force on the first and/or second threaded portions of the stud bolt, in a direction parallel or co-axial to a longitudinal direction of the stud bolt when disposed between the bearing surface and the first or second blade portion.

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).
