Reliability Design Optimization Method for Civil Aircraft Based on Failure Data

Reliability is an important technical index of civil aircraft, which is an inherent quality attribute of civil aircraft and will also directly affect the operation and dispatch. In this paper, the identification and analysis methods of failure data were proposed. The reliability design optimization method and process based on failure data were given. The method to prioritize the reliability design optimization and develop the optimization plan were presented, which could solve the hidden problems or weak links in the design and manufacturing process fundamentally, and improve the whole life cycle reliability and market competitiveness of the aircraft.
