| 摘 要： | 采用隐式有限体积TVD(总变差减小)数值格式，在超声速条件下数值模拟了某空心弹丸绕流流场。系统研究了流场波系结构与空气阻力特性，证实空心弹丸阻力系数比普通弹丸小得多，同时发现发射角度对于空心弹丸的速度降影响不大。

| Abstract: | Complicated flow structure and aerodynamics characteristic were studied after the flowfield of a hollow projectile was numerically simulated in supersonic condition. The implicit finite volume TVD(total variation diminishing) schemes was applied. It proves that the drag characteristic of a hollow projectile is much smaller than a common projectile and it shows that the fire angle has little effect on the velocity decrease. |
