用数值模拟方法研究弹丸在跨、超音速状态下的气体流动特性，数值模拟的出发方程为三维Ｅｕｌｅｒ方程。数值格式为有限体积的隐式ＴＶＤ格式。数值模拟了船尾形弹丸在跨音速下和尖锥柱裙弹丸在超音速下的流场特征，与文献数据进行了比较，结果令人满意。
The numerical simulation method was used to study the gas flow characteristics of the projectile under the cross-supersonic velocity. The starting equation of the numerical simulation was the Euler equation. The value format is a limited volume implicit TVD format. Numerical simulation of the flow field characteristics of the stern projectile at transonic speed and cone column skirt projectile at supersonic velocity is compared with the literature data and the results are satisfactory.
