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.
