摘要

The Image Pattern Correlation Technique (IPCT) was applied to measure the fan blade deformation of the IAE V2527 engine operating at Maximum Continous Thrust (MCT). The ground test on the DLR research aircraft A320-ATRA was a main part of the DLR project SAMURAI which wanted to use the 'Synergy of Advanced Measurement Techniques for Unsteady and High Reynolds Number Aerodynamic Investigations'. The stereo camera system was fixed in front of the left engine. For certification reasons the correlation pattern had to be projected to the fan by a laser. The IPCT evaluation were improved to cope with the special challenges of the measurement and to enable a comparison with Computational Structural Mechanics (CSM) results finally.
