Initiation of Damage to the Hot Part of Aircraft Turbine Engines

Abstract

Abstract In the paper, the initiation causes of damage to flame tubes of a basic combustion chamber and turbine units, which are the most common in the operation process of aircraft turbine engines (ATE), were presented. They were illustrated with the use of numerous examples of progressing degradation of the surface condition of parts and components of various types of aircraft engines which was found during endoscopic controls. On the basis of the systematic observation results, the process of destruction of the turbine rotor ring blades’ surface was discussed. The attention was paid to the current and still valid evaluation of the aircraft turbine engine’s suitability for further operation, taking into account the specifics of its use.
