Model Deformation Measurements by Stereo Photogrammetry at NASA Ames Research Center

At this meeting I will present an overview of tests where my AOX colleagues and I used stereo photogrammetry to measure model deformations. I will discuss in greater detail two recent tests: the Transonic Truss-Braced Wing in the 11x11 ft TWT and a Rotor in Forward Flight in the LaRC 14x22 ft WT. I will conclude with a discussion of lessons learned and future plans.
