The development strategy and key prognostics health management (PHM) technologies for military aero-engine in China were proposed.First

the development history and corresponding representative features of PHM was briefly reviewed.Then

several key relationships and important issues in PHM technology development worth emphasizing were minutely analyzed

which include the relationship between PHM technology development and the air force military requirements

the relationship between PHM technology development and the technology readiness level

developing PHM technology based on the third generation aircraft platform

introducing PHM into aero-engine full-life management system

and the proposed PHM architecture and composed functions for China air force

etc.After that

the key technologies which should be focused on with high priority in China were proposed.Finally

the factors that constrain the domestic developments of China military PHM technology and the aimed technology developing targets are shortly concluded.
