Research Institution
The object of this research is to develop an in-service life-monitor system for the prediction of the remaining component and system life of aircraft engines. The embedded system will monitor the engines thrust, exhaust gas temperature, the engine efficiency, the speed and the time of operation of the engine in flight. Based upon this data, the life-estimation analog of the system will calculate the remaining lives of the components of the engine and combine these into a prediction of the remaining life of the engine. The calculations will be based on the statistical life distribution of the engine components and their relationship to load, speed, temperature and time. The monitoring device will be built for use with an operational aircraft engine.
