摘　　要：温度是燃油箱耗氧惰化系统适航符合性验证过程中重要指标。基于MATLAB Simulink软件,建立了飞机燃油箱耗氧型惰化系统油箱部件的传质传热模型,并验证其可靠性。在此基础上,分析了惰化系统抽气流量和出口温度对飞机燃油箱气相空间节点温度和燃油节点温度的影响。结果表明:所建立的飞机燃油箱传质传热模型具有较高的可靠性;随着惰化系统抽气流量的增加和惰化系统出口温度的升高,气相空间节点温度随之升高但对燃油节点温度影响不明显。The temperature serves as a crucial indicator in the airworthiness compliance verification process of the fuel tank inerting system.Using MATLAB Simulink software,a mass and heat transfer model was established and validated for analyzing the behavior of gas phase space nodes and fuel nodes'temperatures within an aircraft's fuel tank inerting system under varying conditions such as different gas extraction flow rates or outlet temperatures.The results demonstrate that this developed model exhibits high reliability when applied to analyze thermal characteristics inside an aircraft's fuel tank during its operation with different operating parameters.
