Research on reliability prediction methods for aircraft nacelle systems based on FMEA and FTA
Year: 2025
Type: conference-paper
Abstract: The nacelle system, as one of the critical components of civil aircraft, is used to house the aircraft’s engine, providing structural protection, aerodynamic optimization, and facilitating ground maintenance. Its reliability is directly related to the flight safety and operational efficiency of the aircraft. With the continuous development of the national civil aviation industry, research on the reliability technology of civil aircraft nacelle systems has become particularly important, emerging as a significant research direction in the field of aeronautical engineering. This paper focuses on the reliability study of civil aircraft nacelle systems, establishing a failure FTA diagram, exploring and studying the prediction methods for reliability indicators such as DR, SR, and MTBF of civil aircraft nacelle systems, and conducting quantitative estimates of equipment-level reliability. This provides a theoretical reference for further research on the reliability and safety of civil aircraft nacelle systems in China.
