The present work has been done within the Joint Research Project Blade Tester, which develops an approach for cost-effective, serial integrity tests of rotor blades. At that, manufacturing faults shall be automatically detected, localized and assessed with respect to their impact on the integrity of rotor blades in operation. Several techniques are involved and discussed in the contribution, such as 3D full-scale geometry measurement, structural modelling by the finite element method and model validation, fibre optical sensing, several non-destructive testing techniques and parameter identification on the basis of static and dynamic tests.
