Abstract. Accurate simulation of flow field characteristics within the gap between the slipper and track is essential for the prevention of aerodynamic heat damage to high-speed rocket sleds. A three-dimensional structured mesh was utilized to establish the flow field model in the slipper-track gap, while computational fluid dynamics was employed for simulating the flow field movement. The results revealed that the bow shock wave at the head of the rocket sled has a significant influence on the flow field characteristics within the gap. Specifically, the velocity of the mainstream in the gap initially exhibited an increasing trend, followed by a decreasing trend, and then a re-increase. Conversely, the mainstream temperature displayed a decreasing trend initially, followed by an increasing trend, and then a decrease once more. The air compression within the slipper-track gap resulted in remarkably high temperatures, with the maximum temperature reaching 1160 K at Ma = 4 in the immediate vicinity of the slipper. The current investigation provides valuable insights that can guide future research on the structural characteristics of slippers in high-temperature environments.
