超高速弹箭飞行弹道研究

超高速弹箭在飞行弹道上将会出现表面气动加热烧蚀现象，烧蚀变形将影响作用在弹上的空气动力，从而影响飞行弹道。这种烧蚀变形、气动力、外弹道之间的相互影响、相互变化是在飞行弹道上同时存在、相互依附的，对外弹道求解与普通弹箭有很大区别。对此进行了研究，并对超高速弹箭的飞行弹道进行了数值分析，其结果对今后深入开展这方面研究有一定参考意义。

Study on Flight Trajectory for Hypervelocity Projectiles

The hypervelocity projectiles are easy to come forth aerodynamic heating and ablation phenomena, when they flight. The distortion of ablation will affect air forces acting on the projectiles and their flight trajectories. The ablation distortion, air forces and exterior ballistics are interactional and interdependent. Thus, the flight trajectory solution for the hypervelocity projectiles is great different from general projectiles, and is focused in this paper. A numerical analysis for the flight trajectory was also carried out. Some results concluded are useful for further research.
