Abstract
The fuel temperature is one of the key parameters of the aircraft fuel tank flammability assessment. In order to study the temperature distribution of the aircraft fuel tank and the correctness of the heat transfer model, the MATLAB/Simulink software platform was used to build an aircraft fuel tank thermal simulation model. Entering boundary conditions corresponding to flight experiments, the fuel temperature inside the fuel tank at the compute nodes can be obtained through numerical simulation. The results show that under three different sailing conditions, the simulation results of fuel tank thermal model could preferably coincide with the flight test results and calculation error can be controlled within a certain range. Using this fuel tank thermal model in thermal numerical simulation, aircraft fuel tank thermal characteristics can be obtained accurately, and it can be used for optimization of the fuel tank structure and internal heat source component arrangement in the stage of aircraft design.
