摘要

Acoustic Emission (AE) testing procedures developed during a laboratory blade testing programme have been applied to an in-service wind turbine blade. AE monitoring can both locate and characterise damage processes in blades, starting with non-audible signals occurring due to damage propagation at relatively low loads. The results of this assessment of the potential of blade in-service monitoring are sufficiently encouraging to justify further development.
