Reliability growth test based on mission reliability for hydraulic actuation system

Different from the previous mechanical and electrical products, aerospace hydraulic actuation system operates in very short mission time with high reliability requirement. How to design a suitable reliability growth testing for the hydraulic actuation system is urgent to the engineering. This paper designs the reliability growth testing scheme based on Weibull distribution and censored time. Comparing with the traditional reliability growth test based on the Duane model, the reliability growth testing scheme is content to the real application.
