Modeling and simulation of aircraft siphoning fuel transfer system

Aircraft fuel system is a complex pipe network system, and the performance of components needs to be evaluated and optimized several times during the design stage. The simulation study of components can greatly shorten the development cycle. In this paper, an auxiliary tank fuel transfer system configuration of military aircraft is discussed and AMESim software is used to establish the system model. The characteristics of fuel flow rate in different flight phases are investigated. The results show that the flow rate can meet the engine requirements during the whole flight phase. A testing system is built to get the flow characteristics of fuel transfer valve, and the experimental data is used to verify the simulation method. The dynamic characteristic of the valve is studied, which can provide a reference for engineering design.
