Abstract:
The present disclosure is directed to a method and system to develop finite element (FE) models of as-manufactured turbomachinery blades using a combination of optical topography measurements, mesh morphing and strain gauge measurements. The method and system improves strain gauge to blade tip timing correlation using as-manufactured blade dimensions with finite element modeling.
