为了探讨倾角对侵彻贯穿能力的影响,设计并建立了箔屏靶和泡沫板测试系统,对弹丸以一定倾角侵彻贯穿素混凝土靶后的剩余速度的大小、方向以及姿态角进行测量。结果表明非正侵彻时,弹丸贯穿靶板后的姿态和速度方向都发生了较大改变。研究发现靶板破坏分为为正面的开坑、中间的侵彻通道以及背面的剪切破坏和层裂破坏。靶板正面形成非对称形状坑。倾角越大,靶板正面成坑的非对称性越大。

In order to study the effect of obliquity on a projectile perforating concrete targets, a set of oblique perforation experiments of concrete targets by the projectiles were conducted. The ballistic trajectory, yaw angle, residual velocity and trajectory angle after the projectile perforating the target were acquired using foil screen targets and a foam plate. The experiment results indicate that a yaw angel and a trajectory angle after the projectile perforating the target were induced. It is found that the target damage can be divided into three phases: the crating phase in front of the target, the tunneling phase in the middle of the target, and the shear plugging and spalling phase in the back of the target. It is also found that an inclination crater was formed in front of the concrete target.
