Taking an aero-engine fuel system as the researching object, the main components of the fuel system metering valve unit, electro-hydraulic servo valves, valve characteristic parameters and arithmetic works were analyzed with mathematical models. In the Matlab/Simulink environment, the mathematical models of the key elements and the entire fuel system were established. The calculation was validated with the testing data of different fuel system at the actual working conditions. It can be found that the model simu?lation results are good agreement with the experimental results, and the model can meet the design require?ments.
