Abstract

Systems and methods for detecting damage or defects in wind turbine blades are described. In one embodiment, a sound receiver interior to the blade is used to listen for noise that is associated with the presence of damage or defects that interact with air flowing over the exterior of the blade. In another embodiment, a sound source located within the blade generates sound that is received by one or more sound receivers external to the blade. The received sounds are communicated wirelessly to a data processing system that analyzes the sound data. The results can be recorded, displayed, or transmitted for further processing. The systems have detected cracks and holes as small as one millimeter in diameter. One advantage of the system is that it makes possible preventive maintenance on an as needed or preplanned (scheduled) basis, rather than as an emergency response to turbine blade failure.
