Testability Design of the PHM System for Aero-engines
PHM (Prognostics and Health Management) for Aero-engines is an effective technical approach to balance the economy and safety of the flight in the total life cycle. Testability design is the foundation to implement PHM. In this paper, we mainly analyze the popular issues including the testability design concept, the scheme of condition monitoring and the utilization extent of condition information. Then presents some useful solutions and advices for the testability design respectively; and analyzes the influence of testability on health management strategies and the main source of uncertainty; and propose a roadmap for making test program based on the PHM requirements and evaluating test program, for improve the utilizing degree of monitoring information, Lastly some common data fusion methods and some typical examples is illustrated.
