A long cylindrical self-propelled underwater projectile that detonates on contact with a target. 一种长筒状水下自推引爆目标的射弹。
The equations group of launch dynamics for self-propelled artillery is formed, including the body dynamics equation of gun system, the dynamics equations of projectile moving in gun tube and the equations of the two-phase flow interior ballistic. 建立了完整的自行火炮系统发射动力学方程组,包括火炮系统的体动力学方程组、弹丸在膛内运动的动力学方程以及两相流内弹道方程。
For a self-propelled artillery the computational program is achieved, by which the simulation of launch process is realized. The interior ballistic, motion of projectile in gun tube, dynamic response of the artillery and initial disturbance of projectile are exactly simulated. 编制了计算程序,实现了对某自行火炮发射过程的数值模拟,在准确计算内弹道过程的同时,获得了火炮的动力响应、弹丸膛内运动和起始扰动。
