Implications of engine's deterioration upon an aero-engine HP turbine blade's thermal fatigue life

Possessing a better knowledge of the impacts of engine deterioration upon an aircraft's performance as well as its fuel and component life usage, helps the users make wiser management decisions and hence achieve improved engine utilization. For a military aircraft, using a computer performance simulation, the consequences of engine deterioration on a high pressure turbine blade's thermal fatigue life are predicted.
