Fixed-Wing Aircraft Reliability Assessment Database Design

Aircraft reliability level is one of the important indexes that need to be assessed after the completion of aircraft design, and a large amount of reliability information will be generated during the whole life cycle of fixed-wing aircraft, and it is particularly important to construct a reliability assessment database to store and analyze new data on the reliability of fixed-wing aircraft. This paper discusses the collection of aircraft reliability assessment data from engineering practice, gives a mathematical model of reliability assessment and gives examples to verify, and puts forward the general process and method of reliability assessment database design, which can provide reference for fixed-wing aircraft test reliability assessment.
