Research On Mpa Method In Ehm System

Aircraft Engine Health Management (EHM) System deals with the monitoring, detection, isolation, trend prediction and accommodation of engine degradation, faults, and failures. Minimizing total cost of engine ownership, increasing asset availability/ mission readiness and while maintaining or even increasing safety are the key drivers for the implementation of EHM System. This paper investigates the function, basic principle and analysis process of module performance analysis (MPA) method in aircraft engine health management (EHM) system. The development trend of MPA in future is also prospected.
