Abstract
A method is proposed for the automatic inspection of jet engine turbine blades usingtransient infrared thermography. The blades are thermally stimulated using air internal flow at different temperatures. By looking on the pressure side of the blade, it is possible to detect and locate blocked cooling passages. This analysis has been automated through the study of the time response of the blades.
