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.
