Stiffness Properties Improvement of Wind-Tunnel Structural Models

Wind-tunnel testing allows to verify predicted pressure distributions in various configurations on a specific model. For this verification to be successful, both the model deformation and the air flow needs to be predicted accurately. Modern wings tend to be thinner, thus more flexible and deform more under the loads applied in the wind-tunnel. Current methodologies exist to assess these structural properties outside of the wind-tunnel through static mechanical testing. The process is tedious and prone to errors. The goal of this project is to leverage Digital Image Correlation, a non contact measurement method, to accurately measure wing deformations resulting from a known load. This information can be used to re-construct a stiffness simulation model that can reproduce the full wing behavior.
