应用图像相关技术(IPCT)对IAE V2527发动机在最大连续推力(MCT)工况下的叶片变形进行了测量。德国航空航天中心研究飞机A320-ATRA的地面测试是德国航空航天中心武士项目的主要部分，该项目希望利用先进测量技术的协同作用进行非定常和高雷诺数空气动力学研究。立体摄像系统固定在左侧发动机的前面。出于认证原因，关联图案必须通过激光投射到风扇上。改进了IPCT评估，以应对测量的特殊挑战，并最终能够与计算结构力学(CSM)的结果进行比较。
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.
