| Aeroengine Health Management is a key technology to improve the safety，reliability and affordability of contemporary ad?
vanced aeroengines，it is one of the most important methods to realize condition based maintenance strategy. As an important supporting technology of the health management system，aeroengine gas path fault diagnosis has important research value and prospects in the development of advanced aeroengines. Based on the development results of aeroengine gas path fault diagnosis for more than 50 years，the overall implementation process of gas path fault diagnosis was reviewed，including the selection of gas path measurement parameters，parameter preprocessing，calculation of baseline values and baseline model construction methods ，followed by basic principles and typical achievements of model-based and data-driven method and comments of the characteristics of different methods. Finally，the future development direction of gas path fault diagnosis，including performance prognostics，online gas path fault diagnosis，information fusion and transient state
gas path fault diagnosis was proposed，the basic ideas and research status of these problems were analyzed. Public research shows that aeroengine gas path fault diagnosis has formed a model-based and data-driven diagnosis method system，and has achieved a comprehensive and systematic development. Based on the existing research results，it is suggested that further improvement should be implemented in China，including improving the collection and collation of aeroengine life-cycle data，establishing the design system of Engine Health Management system，as well as strengthening the collaboration among industry，academia，research and application ，thus providing strong technical support for advanced aeroengine health management system. |
