Aviation PHM System Research Framework Based on PHM Big Data Center

Aviation Prognosis and Health Management (PHM) is an important measure to improve the security, reliability, testability, maintainability and supportability of aircrafts. The development of aviation PHM system has been widely concerned. However, the design framework of aviation PHM system in various countries at present is not uniform, the engineering application is relatively backward, and many technical or engineering problems intersect with each other, which restrict the clear understanding and technology development of aviation PHM system. This paper puts forward a new way of thinking in aviation PHM framework design which is based on the PHM big data center, which helps to understand aviation PHM comprehensively. In detail, the key technologies, scientific problems and application systems of its engineering proposal are demonstrated. All of these provide references for the research and development of aviation PHM system.
