FIELD: physics.
SUBSTANCE: retaining device for test tip of turbine blade matched to exterior geometrical shape of test section of turbine blade surface is mounted. This retaining device is notched to position the test tip then attached to test estimator and measure with using multiple-emitter (phase-locked array) ultrasonic inspection procedure. Thus ultrasonic pulse signal is radiated, while echo signal caused with flaw or element edge reflections is accepted and then compared to reference echo signal. Flaws are located through estimating differences between echo signal and reference echo signal.
EFFECT: ensured reproduced ultrasonic inspection of mounted turbine blades.
