摘要

This paper focuses on the reliability of electric drive systems in electrified aviation, considering thermal, electrical, ambient, and mechanical factors alongside conventional aviation technologies. It reviews degradation mechanisms in conventional gas turbines, fuel cell and battery systems, power electronics, and electric motors. Moreover, the study recommends employing a physics-of-failure approach to analyze the reliability of components and subsystems within electric drive systems. By using tools commonly utilized in aircraft construction and certification for reliability assessment, the paper demonstrates the feasibility of evaluating and improving the reliability of all-electric architectures.
