Paper Abstract

Pulsed Laser Electronic Speckle Pattern Interferometry (ESPI) is close to a real-time experimental method of analysis of component deformation. In-plane displacement and strain information may be obtained over a wide range of rotational speeds. Liquid crystal material sprayed on to the component surface gives a clear transitional colour change at specific temperatures for windage heating effects at high speed and may be suitable for temperature distribution measurements.
