用数值模拟方法研究弹丸在跨音速、小攻角状态下的流动特性．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．通过数值模拟，研究了弹丸在Ｍ∞＝０．９６和Ｍ∞＝１．１，攻角α＝４°状态下的流场特征，结果显示，弹体表面产生明显的非对称激波．计算得到的弹体表面压力与实验数据进行比较，结果令人满意．
The numerical simulation method is used to study the flow characteristics of the projectile under the conditions of transonic and small angle of attack. The starting equation of numerical simulation is the three-dimensional Euler equation. The value format is a limited volume implicit TVD format. Through the numerical simulation, the flow field characteristics of the projectile under M∞ = 0.96 and M∞ = 1.1 and at the angle of attack α = 4 ° are studied. The results show that the surface of the projectile has obvious asymmetric shock waves. The calculated surface pressure of the projectile is compared with the experimental data and the result is satisfactory.
