Measurement of vibrations of a wing

Abstract

In the paper vibrations of a wing are investigated experimentally by using the method of time averaged projection moiré. Experimental setup is developed and the results obtained by using the experimental procedure are analyzed. Interpretation of projection moiré images on a shallow surface is more complicated than on a plane surface. For this purpose, a special simplified two‑dimensional numerical model is developed and used in hybrid experimental – numerical procedures of investigation of vibrations of a wing.
