This study conducted a basic study on the cooling performance of the scramjet regeneration cooling considering the aspect ratio (AR) for the optimal design. The cooling performance according to the aspect ratio of the regenerative cooling channel was checked by reflecting the aerodynamic heating and combustion heat generated from the flow during the flight at Mach 6 for 600 seconds. The regenerative cooling channel inside the scramjet aircraft was reflected in one dimension, and the heat transfer model was applied to calculate the heat transfer coefficient. The heat transfer analysis method was verified by comparing it with the cooling channel experimental data, and finally, the cooling performance was compared considering the regenerative cooling channel AR of 1, 2, and 4.
