| 摘 要： | 传统的超空泡射弹尾拍力求法将空泡边界看成是一条直线，在求解弹丸浸入长度时势必造成误差，导致弹丸的尾拍力求解不精确，本文主要在传统求解浸湿长度的基础上提出了一种改进型的求解方法，将空泡壁看成是椭圆的一部分。仿真结果显示，改进后尾拍力变大，弹丸衰减速度变快，弹丸空化器上的阻力变小。

| Abstract: | Regarding vacuolar boundary as a straight line, the error is caused during solving projectile immersed length, and the projectile tail slap strive is imprecise. An improved method is put forward based on the traditional method of solving immersed lengthen, in which regard vacuolar wall as part of the ellipse. The simulation results show the shot force of tail become larger, projectile decay becomes faster and the resistance of projectile cavitator becomes small after improvement. |
