Comparison of MDM methods at ETW (EWA) (Part II)

Abstract

The Model Deformation Measurement (MDM) methods of DLR, Onera and ETW have been compared in a wind tunnel test conducted within the EWA workshop “Measurement of wing deformation at ETW”. The participating partners used the same stereo camera system, but different calibration procedures were applied. The introduced MDM method “Image pattern correlation Technique” (IPCT) uses a random dot pattern instead of discrete markers which are used as targets by the MDM method of ONERA and ETW. The comparison of the results for the different methods showed a good consistency
