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 The geometry of the tail-shell shelled armor-piercing projectile is very complicated. It is often difficult to study the aerodynamic interference between the shell and the projectile. Thompson method was used to generate grids in the first subdivision of the computational domain and then combined to obtain a reasonable grid system that can be used to numerically simulate the disturbed flow field when the shells are separated from the projectile. The method is simple and convenient, and the grid generation converges fast
