    Abstract: An apparatus 100 for determining orientation of a segment 32 and 30 of a wind turbine blade 28 is disclosed. The apparatus includes an elongated member 1 and a support plate 2 provided at one end of the elongated member 1. The support plate 2 is defined with one or more provisions 4 to facilitate connection with the segment 32 and 30 of the wind turbine blade 28. Further, a measuring plate 3 is provided at another end opposite to the one end of the elongated member 1, where the measuring plate 3 is defined with a substantially airfoil profile 35. The measuring plate 3 includes a plurality of markers 18 disposed along an airfoil region 34 where, each of the plurality of markers 18 is indicative of one or more of multiple parameters to determine the orientation of the segment 32 and 30.
    FIG. 6 is the representative figure.

    Abstract: The present invention relates to a method of manufacturing a wind turbine blade (10), comprising the steps of placing a fibre lay-up including one or more fibre layers on the mould surface of a blade mould (60), arranging a load-bearing structure (45) and a core member (62) on the fibre lay-up such that the core member (62) is arranged between the load-bearing structure (45) and the leading edge (18) and/or between the load-bearing structure (45) and the trailing edge (20), and infusing resin into the blade mould to impregnate the fibre lay-up. The core member (62) comprises a first hole (64) with a circular cross section, a first cylindrical insert (70) rotatably arranged within the first hole (64) of the core member (62), the first cylindrical insert (70) having a central axis (71). A recess (80) is formed in the first cylindrical insert (70), wherein the recess (80) is arranged eccentrically with respect to the central axis (71) of the first cylindrical insert (70).
