Preliminary Investigation of the Use of Holographic Interferometry to Detect Ill-Fitting Compressor Blades.

Abstract

The technique of double exposure holographic interferometry has been used to detect and investigate ill-fitting compressor blades. A brief introduction to holographic interferometry is given. Holographic interferometry has enabled the observation of the displacements of blades when the blades are subjected to a small force. The potential of a pulsed laser holographic system to be used for in-situ investigations is discussed. Keywords: Holographic interferometry Nondestructive testing; Gas turbine engines. (Australia)
