Infrared detection of defects in wind turbine blades

A method and an apparatus for detecting defects in the composite materials of a wind turbine blade or similar type of structure using an infrared (IR) camera. The temperature of the wind turbine blade is changed in such a way as to produce IR intensity changes in the region of the defect that can be...

Zusammenfassung:A method and an apparatus for detecting defects in the composite materials of a wind turbine blade or similar type of structure using an infrared (IR) camera. The temperature of the wind turbine blade is changed in such a way as to produce IR intensity changes in the region of the defect that can be visually detected or detected using a computer and signal processing algorithms. The same approach will work on other composite structures such as those found on aircraft.
