Abstract

A system (100) may include at least one computer device (104) configured to attain a two-dimensional used profile of a leading edge at a specified radial position on a turbomachine airfoil after use. The system (100) aligns opposing substantially straight alignment portions of the two-dimensional used profile with opposing substantially straight alignment portions of a previously attained, two-dimensional, baseline profile of the turbomachine airfoil. The alignment portions of each profile are in substantially identical radial locations of the turbomachine airfoil. Comparing the used profile to the baseline profile determines whether the leading edge at the specified radial position of the used turbomachine airfoil has erosion. The system may also include a laser profiler (130) for measuring the turbomachine airfoil (132).
