【 摘 要 】

In order to explore the variation rule of the projectile's flying state in the process of projectile penetrating into multi-target, the numerical simulation of 60mm calibre projectile penetrating multi-layer C40 concrete target is carried out. The effect of the initial velocity and initial angle of attack on the ballistic deflection is studied. The variation trend of the posture of the projectile with time and the changing trend of the velocity with time are obtained by numerical simulation, and then the changing law of the angle of attack is obtained. From the result, we can get that the attack angle of projectile can be divided into several stages when penetrating into a single target, and the bigger the initial attack angle is, the more obvious the change is.
