Abstract

The RADAC (Recovery of Attitude and Deformation by Crossed Anamorphoses) system was developed to enable precise measurement of wind tunnel model deformations under aerodynamic loads. The system was developed by the Centre d'Etudes et de Recherches de Toulouse to meet high Reynolds Number testing requirements of the ONERA large wind tunnels. This document presents a summary of the measurement principle. The design and implementation of the system for use in the ONERA S1 wind tunnel is then discussed. Finally, experimental results from development tests and qualification testing in the S1 tunnel are presented.
