Optimization of the Ultrasonic Control of the Wall Thickness of the Blades of Gas Turbine Engines

Abstract

Ultrasonic detection is widely used for the control of a gas-turbine engine details. This method is available for the material continuity and details thickness checking, being based on a detection and evaluation of an ultrasonic signal parameters, reflected from the substance discontinuities and details coverings. Echo- pulse method is most widely used by this time.
