Abstract: It takes very important role that aeroengine load and life monitoring technology in monitoring and assessing operating condition, life consumptiom and remaining life of aeroengine. It can improve the safety and reliability, and reduce direct usage cost of engine. In this paper, the life usage monitoring system is including data condensing processing,LCF counting for every flight and Low Cycle Fatigue, Thermal Fatigue, Creep, and any combination of them can be dealt with. The information obtained by life monitoring system is very useful for the database of part management which will be used to track the life usage of the engine parts.
