| 摘 要： | 采用计算流体力学方法结合动网格技术建立了双管火炮异步发射时膛口流场的二维数值模拟模型,正确描述了双管不同步发射时炮口流场的激波系结构的形成﹑发展与相互干扰的过程。模拟结果得出双管不同步发射时对弹丸飞出膛口后的飞行姿态影响较大,从而弹丸偏移速度会影响双管火炮的射击精度。

| Abstract: | This paper combined computational fluid dynamics with dynamic mesh techniques to establish the two-dimensional numerical simulation model of the muzzle flow field of double-barreled gun firing at intervals,and correctly described the formation and the development of the shock wave system in the muzzle flow field,and the process of mutual interference.The results show that the muzzle flow field has large influence on the flight state of the projectile when it departs muzzle,thereby,the migration velocity of projectile will affect the shooting accuracy of double-barreled gun. |
