Target Recognition Using Neural Networks for Model Deformation Measurements

摘要

At the NASA Langley Research Center, airfoil models are placed in environmentally controlled wind tunnels for aerodynamic testing and are subjected to pressure and temperature extremes. Aerodynamic loads are applied to the test specimen, and forces, moments, and other model parameters are measured directly. However, some properties, such as model twisting and bending, must be measured indirectly to avoid interactions with the test article. Optical measurement systems provide a nonintrusive solution for these applications.
