Abstract

In the wind tunnel testing, structural deformation and motion should be measured using non-contact and precisely calibrated techniques. We designed, developed, and set up a novel DIC method for testing large and lightweight structures in wind tunnel. With the use of a universal mount mechanism and optical advancements for far-field structural evaluations, we increased the functionality of our current in-house stereo DIC system. The pitch and azimuth rotations of cameras are taken into consideration during the calibration of the WT-DIC system utilizing the Euler rotation theorem. Case studies for the developed DIC system include a small MAV flapping wing and a large deployable parachute.
