Abstract

This paper presents a new method for measuring twist deformation of turbine blades in rotating which is known as optical pulse interval method. The measurement divices are more convenient for field measurement. The accuracy of this divices is better than 0. 05 . It is ten times more than the accuracy of the superspeed photogrammetry. The method is potencial to measure torsinal deformation of other rotating machines. !
