Study of Moire Measuring Techniques for Wind Tunnel Model Deformation

Abstract

Moire pattern measurement techniques for measurement of changes in the shape of aerodynamic models during wind tunnel tests was investigated. Theoretical and experimental study resulted in a recommendation of a Moire system with a major variation. The grid is physically applied at the model surface. Images are recorded on film in two views for both the distorted and undistorted cases. These images are then processed to determine the position of the grids in the undistorted condition as well as the magnitude of the distortion suffered by the grids during the test.
