摘　　要：为了计算机翼油箱内燃油温度场的分布随燃油消耗的变化情况,建立了机翼油箱内燃油温度的传热模型和油箱燃油消耗的两相流模型,计算了不同飞行高度、马赫数和机翼油箱输油速率条件下燃油温度场的分布情况,并将计算结果进行对比分析。本文的计算结果在飞机燃油系统的设计阶段对油箱内热源和燃油温度传感器的安装位置具有指导意义,在飞机燃油系统的飞行试验阶段对飞行试验方法设计具有借鉴意义。In order to calculate the change of fuel temperature field distribution with fuel consumption in the wing tank,we established the heat exchange model of fuel temperature and the two-phase flow model of fuel consumption,and analyzed the fuel temperature field distribution under different altitude,Mach number and fuel transfer speed.The results of this study are of guiding significance for the installation position of heat source and fuel temperature sensors in the designing stage of aircraft fuel system,and are of reference significance for test method design in the flight test stage.
