Operation-Related Failures of Aircraft Turbine Engines

Abstract:

The paper is intended to draw attention to the most frequent reasons that lead to initiation of failures to components of flame tubes incorporated into combustion chambers and turbine units during the operation lifetime of aircraft turbine engines. These failures are illustrated by means of numerous examples that disclose gradual deterioration of components and subassemblies detected on their surfaces during endoscopic inspections carried out on various types of components and subassemblies of aircraft engines. The mentioned deterioration process affecting blade surfaces of turbine blade rims is analyzed on the basis of continuous monitoring that has been carried out to date. Attention is also paid to the way how aircraft engines have been so far and keep being evaluated whether or not they suit for further operation with consideration to specific features of service.
