A Simulation Software of Prognostics and Health Management for Aircraft Fuel System
This paper aims to develop a simulation software of prognostics and health management (PHM) to carry out research on the method of diagnostic, prognostic, and health management for fuel system. The software is able to simulate the aircraft fuel flow performance such as pressure variation, flow rate in the fuel system pipe network both on the fuel system normal status and its malfunction status. When a failure mode of a component such as radial pump, ball valve happens, the nodes which maximum pressure variation has happen in the fuel system pipe network are selected, and the virtual sensor is arranged in these nodes. Through the signal correlation comparison of these virtual pressure sensors, the failure mode is diagnosed and prognosed. Since the PHM methods is not mature at present, and its false alarm rate is fairly high, the software can verify and study the novel PHM methods, which will supply technical support for the onboard aircraft PHM system in the future.
