| 摘 要： | 尾翼脱壳穿甲弹的几何外形十分复杂，给研究弹托和弹体之间的气动干扰工作常带来很大困难．运用Ｔｈｏｍｐｓｏｎ方法和计算域先分块生成网格，然后拼结，获得可用来数值模拟弹托从弹体上分离时干扰流场的合理网格系统．该方法简单方便，网格生成收敛速度快 |
| 关 键 词： | 尾翼脱壳穿甲弹，外弹道学，网格生成，Thompson方法 |

| Abstract: | The complicated geometry configuration of APFSDS usually makes many difficulties for the studies of a sabot and a projectile aerodynamic interaction. In this paper, a rational mesh system for the investigation of interaction fluid fields caused by a sabot separating from a projectile using Thompson method and computational domain blocking at first, then putting each zone together has been obtained. This method is simple, and its converge rate is fast. |
