摘　　要：基于Flowmaster2软件建立了某型飞机燃油系统的整体仿真模型,并进行了瞬态和稳态分析。在瞬态分析中得到几个压力值较大的节点,在稳态分析中得到个别流速流量均出现较大幅值的元件,并且得到发动机入口流量完全符合设计要求。分析结果均可以对该整体系统较好的进行流体力学行为描述,同时为改进和优化设计燃油系统提供了新思路和方法。The integrated model for airplane fuel system is established using Flowmaster2 software. The analysis of steady state and transient state for this system are carried out. The analysis results are good for this system at two states and some modified suggestions are proposed. Some points with great pressure value at the transient state analysis are discovered. Some components with bigger flow rate are obtained at the steady state analysis. The flow rate of engine entrance accords with the design. Through modeling and simulation of pipe network system, new method is provided for modifying and optimizing fuel system.
