Abstract:

Developing gas path-based health management technology for aero engines is crucial for improving engine safety and minimizing maintenance costs. This paper begins by introducing the evolution of gas path-based health management technology for aero engines. It then systematically summarizes the current research on gas path fault diagnosis methods based on the classification of model-driven, data-driven, and hybrid-driven approaches, and presents the data-model hybrid driven fault diagnosis method. Additionally, the paper reviews aero-engine modeling methods, aero-engine sensor fault diagnosis methods, and aero-engine gas path performance prediction techniques, discussing their characteristics, advantages, and limitations. Finally, the paper concludes by summarizing the emerging trends and challenges of aero-engine gas path fault diagnosis technology. Hybrid-driven methods demonstrate significant potential in enhancing the accuracy, generalization, and engineering applicability of gas path fault diagnosis, providing new directions for health management under complex operating conditions.

Key words: hybrid method, aero engine gas path fault diagnosis, sensor fault diagnostics, data-driven methods
