基于全球鹰无人机的机翼油箱输油方案研究

Studying Three Schemes for Wing Fuel Tanks in UAV Fuel System

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。

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 entided transient-state simulation and the analysis of simulation results; its core consists of： （ 1 ） we propose three schemes; （2） we present the simulation results of the 1st scheme in Figs. 7 and 10; （3）we present the simulation results of the 2nd scheme in Figs. 8 and 11 ; （4） we present the simulation results of the 3rd scheme in Figs. 9 and 12; （5） Fig. 13 compares the simulation results of the three schemes; （6） we analyze the merits and demerits of the three schemes.
