基于全球鹰无人机的机翼油箱输油方案研究

文章针对全球鹰高空长航时飞机设计了机翼油箱的三种输油方案,建立了燃油系统仿真模型.对三种输油方案模型进行了稳态和瞬态仿真,通过对三种机翼油箱输油方案的节点压力、输油流量及供油泵出口压力的比较,分析了不同输油方案的优缺点,该研究对高空长航时类飞机燃油系统的研究具有实用的参考价值.

Studying Three Schemes for Wing Fuel Tanks in UAV Fuel System

Sections 1,2 and 3 of the full paper explain the results of our research,which take into consideration of what is known about the U.S.Global Hawk UAV.Section 1 is entitled establishment of the model of the fuel system;its core is Fig.1,which shows the positioning of wing fuel tanks.Section 2 is entitled the steady-state simulation and the analysis of simulation results;its core is Fig.6,which shows the node pressure curve.Section 3 is entitled transient-state simulation and the analysis of simulation result...
