Abstract: This paper deals with a method of diagnostics and focuses on the estimation of the depletion or exhaustion of service life of components of gas turbine engine. During operation of the gas turbine engine the critical components of the engine; blades, discs, shafts, wheels, gears, gearboxes and drive assemblies experience the action of centrifugal and gas forces that bring about tension, bending and turning moments. They also experience thermal loads of high intensity that has negative effect on the strength of the materials of the components. The strength of these components defines the reliability of the engine. The forces and thermal loads acting on the critical elements lead to the depletion of the service life of these elements. Hence the estimation of the remaining service life of gas turbine engine components.

Keywords: Blades, critical components, damage, depletion, gas turbine engine, failure, service life, typical flight
