“…Lightweight structures are highly recommended in aerospace applications such as flapping wings in MAV (Micro air vehicle), deployable parachutes, gossamer structures, and inflatable space structures due to their flexibility, adaptability, fatigue resistance, and stability in extreme environments. [1][2][3][4] Large test sections of wind tunnels are used to test the aerodynamics of these structures. For measuring force and moment, conventional techniques like sting balances and robotic arms are well-established.…”

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.

“…9 Moreover, structural deformation caused by aero-structural interactions needs to be recorded in real time. 3 For far-field structural measurements, we designed and created an effective, high-resolution DIC system with an adjustable mounting mechanism. This system may be deployed from outside the enormous tunnel section walls.…”
