| 摘 要： | 飞机燃油系统作为飞机不可或缺的功能和保障系统,对飞机的安全性有着重大的影响。针对飞机燃油供油系统的故障诊断问题,利用流体仿真软件Flowmaster建立了供油系统模型。仿真了飞机燃油系统增压泵供油、交输供油、重力供油的工作情况。分析了飞机燃油供油系统的故障模式,仿真了在几种典型故障模型下的工作情况,并对仿真结果进行了分析。结果表明利用Flowmaster所建立的供油系统模型能有效地仿真飞机燃油系统正常与故障工作情况,为飞机燃油系统的故障诊断打下了基础。

| Abstract: | Fuel system as an integral function and security system of aircraft has major impact on the safety of aircraft. Aiming at the problem of failure diagnose, the model of aircraft fuel feeding system is built by fluid simulation software Flowmaster. The aircraft fuel system working at the condition of boost pump feeding, cross-feeding and gravity feeding are simulated. The fault mode of aircraft fuel feeding system is analyzed. The working conditions of several typical failures are simulated, and the results are analyzed. It shows that the fuel feeding system which is built by Flowmaster could simulate the aircraft fuel feeding system working at normal or failure conditions. The result provides a foundation for the failure diagnose of aircraft fuel feeding system. There is much engineering application value. |
