Abstract (en)

[origin: WO2022172011A1] A blade, such as for a wind turbine generator, comprises first (18) and second (22) shells, and an internal shear web (12) spanning between the first (18) and second (22) shells. During manufacture, the shear web (12) is firstly bonded into the first shell (18). Next, adhesive (20) is applied to a flange (14) of the shear web (12) and to the leading edge and trailing edge of the first shell (18). The second shell (22) is united with the first shell (18) and bond lines of the adhesive (20) are formed along the shear web flange (14), leading edge and trailing edge. The blade assembly is heated to cure the adhesive (20), and a monitoring device (30) within the blade monitors displacement of the second shell (22) with respect to the shear web (12) while the adhesive (20) cures.
