摘要

摘要:
为研究飞行包线下飞机燃油箱燃油温度的变化情况，基于AMESim仿真平台建立了燃油箱热模型，以某飞行试验对应的边界条件为输入进行计算以验证模型的准确性，在此基础上分析了暖天飞行任务及不同转输油模式下各燃油箱燃油温度变化规律。结果表明：该仿真模型计算结果与飞行试验数据吻合良好，满足适航符合性验证的精度要求；在爬升和巡航阶段，中部油箱燃油温度始终高于其他油箱，机翼油箱由于外界环境的冷却作用燃油温度较低；转输油模式对中部油箱和集油箱燃油温度变化影响较大，在转输油模式2下各燃油箱燃油温度差异较转输油模式1更小。

Abstract:
In order to study the fuel temperature change rule of aircraft fuel tank under the flight envelope, a fuel tank thermal model was established based on the AMESim simulation platform, and the boundary conditions corresponding to a flight experiment were used as input for calculation to verify the accuracy of the model. On this basis, the change rule of fuel temperature in each fuel tank under a hot day flight and different fuel transfer modes was analyzed. Results showed that the calculation results of this model were in good agreement with the flight experiment data, and met the accuracy requirements of airworthiness compliance verification; during the climbing and cruising stages, the fuel temperature in the middle fuel tank was higher than other fuel tanks; the wing tank fuel temperature was at a relatively low temperature due to the cooling effect of the external environment; the fuel transfer mode had a greater impact on the fuel temperature changes in the middle fuel tank and collection fuel tank, and the fuel temperature difference of each fuel tank in the fuel transfer mode 2 was smaller than that in the fuel transfer mode 1.
