Abstract

The results of studies are presented of fatigue-determined failure causes of the blower impeller of aircraft gas turbine engine core based on vibration mode patterns obtained by the holographic interferometry. Recommendations for detuning from the resonance are given that allows the part destruction to be eliminated.
