    Abstract

  • 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.
