THE ESTIMATION OF RELIABILITY OF TITANIUM GAS TURBINE ENGINE SEMI-FINISHED CRITICAL PARTS AUTOMATED ULTRASONIC TESTING WITH MATHEMATICAL MODELLING
(pp. 54-63)

Abstract. Questions of titanium gas turbine engine semifinished critical parts automated ultrasonic testing reliability estimation with mathematical modelling oftesting process are observed. Limitations of the previous approach based on specimens with synthetic defects experimental researches are described. The choice method of hard alpha model geometrical parameters and orientation which consider inspected semifinished part form and manufacturing process is offered. Also the algorithm which consider morphological features of natural hard alpha inclusions is offered.

Keywords: automated ultrasonic testing, hard alpha inclusions, ultrasonic testing probability of detection, ultrasonic testing optimal parameters, mathematical modeling.
