Spin Pit Application of Image Derotated Holographic Interferometry.

Abstract

This report describes the results of a program in which an experimental technique for image derotated holographic interferometry was developed to investigate the resonant response of a gas turbine engine bladed-disk assembly under controlled laboratory conditions of rotation and vibratory excitation. Image derotated holograms were taken for several modes of vibration of a rotating bladed disk at speeds up to 7,500 rpm in a laboratory spin test facility. (Author)
