Research on reliability test scheme of restoration task of civil aircraft landing gear

Abstract

Abstract: In order to meet the requirements of airworthiness authorities concerned about the civil aircraft landing gear reli鄄 ability test, the conversion relationship between landing gear restoration task interval and corresponding failure rate is analyzed based on the fault law of civil aircraft landing gear. Then, the reliability test scheme of civil air鄄 craft landing gear based on Bayes theorem is formulated. Prior information is properly used to determine the prior distribution of product failure rate. On this basis, the improved scheme is proposed, referred to the calculated posterior distribution and the given user risk. The experimental results show that the improved scheme can re鄄 duce the required sample size and test time on the premise of meeting the requirements proposed by airworthi鄄 ness authorities, as well as maintaining the test confidence, compared with the classical statistical test scheme.

Key words: landing gear, restoration task, Bayes theorem, failure rate, posterior distribution
