Experimental Investigation on the Damage Characteristics for Light Armored Vehicle by Large Caliber Rifle Projectile

Abstract

Large-caliber multi-function rifle projectile is one of the main weapons used by the army to attack light armored vehicles. The damage of the bullet to light armored targets is not only the direct killing effect of bullets hitting the target, but also the flames and fragments formed by the penetration process. In this paper, the impact effect of a large caliber multi-functional bullet on light armored vehicles with different firing distance is studied by experiments. By reducing the charge to simulate the shooting at different distances, rifle projectiles with different speed penetrate 10 mm armor plate, and the formation process of after-effect fragment and flame is captured by high-speed photography. The flying angle, flame length and flame time can be observed from the high-speed photographic image. Through data processing, the spatial range of the after-effect fragment and flame was obtained. The research results showed that there was a positive correlation between fragment speed and penetration velocity, the after-effect fragment dispersion and the flame length are not very sensitive to the distance, and the flame size at the distance of 100 m is up to about 50% than 400 m, the flame action time at 400 m is 4.62 times that of 100 m, and the flame reached the brightest time at 400 m is 10.29 times that of 100 m.
