Abstract
The surface condition of the leading edge of rotor blades has a significant influence on the lifetime and performance of a wind turbine. The delayed detection of erosion damage results in high maintenance and repair costs. Therefore, a non-destructive in situ measuring method is required for the early detection of erosion damage and initial subsurface. Active thermography fulfills these requirements. First measurement results show that it is possible to visualize damage patterns on rotor blades and to make initial subsurface defects, which often lead to premature erosion, visible.
