Nose ablation shape influences the lift-drag ratio and the stability of a hypersonic aircraft. For the integrated design of long-time gliding aircraft, it is of great significance to evaluate the ablation shape of the nose-tips accurately. The calculation method of nose ablation shape is introduced. Simulation research of hypersonic aircraft's ablation shape is conducted based on this method. The simulation and experimental results of an aircraft nose ablation are in good agreement with each other. The ablation shapes during pitching and rolling motion are compared. Estimation of ablation shapes with flight status has been studied thoroughly. Pitching motion affects the ablation thickness on windward and leeward side, and roll motion affects the ablation position.
