Aero Engine Remaining Useful Life Prediction: A Survey

Aero-engine remaining useful life prediction is critical for improving aircraft reliability and reducing maintenance costs. However, aero-engine RUL prediction faces many challenges, including the effects of multiple operating conditions, insufficient data, and the difficulty of real-time prediction. In this paper, we review RUL prediction methods for aero engines. In addition, we summarize the existing aero-engine-related datasets, common data processing techniques, evaluation criteria, and performance comparisons of some existing methods. Finally, the current challenges and future trends of aero-engine RUL prediction are summarized.
