For real-time health monitoring of aircraft engine
components and systems
This project developed an inservice life-monitoring system capable of predicting the remaining component and system life of aircraft engines.
The embedded system provides real-time, inflight monitoring of the engine’s ASTEC photo NASTEC photo thrust, exhaust gas temperature, efficiency, and the speed and time of operation. Based upon this data, the life-estimation algorithm calculates the remaining life of the engine components and uses this data to predict the Phase II Objectives remaining life of the engine. The calculations are based on the statistical life distribution of the engine components and their relationship to load, speed, ` Acquire profiles of aircraft system temperature, and time.
