摘要
燃油系统在飞机上是一个非常庞大而且复杂的系统。利用流体仿真软件F lowm aster构建了飞机燃油系统整体模型,并进行了一系列仿真分析,分别追踪了管路系统在正常情况、某一(些)增压泵失效、一发动机失效时发动机入口流量和压力随时间变化曲线,并与设计流量和压力进行对比分析,发现计算结果满足设计要求,证明这种方法是切实可行的。
Fuel system is a very enormous and complicated system in an aircraft. In this paper, the whole aircraft fuel system model is established for Flowmaster （ a fluid simulation software） and a series of simulation analysis for this model are proceeded. The engine input flow rate ＆ time curve and input pressure ＆ time curve are tracked in the case that fuel pipeline system is as usual, that some pump is in failure and that some engine is in failure. Then those curves are compared with designed input flow rate ＆ time curve and input pressure ＆ time curve. The results satisfy design demands well, this shows that this analytical method is feasible.
