摘要
针对高速侵彻弹体提出了一种全新的花瓣形头部刻槽结构,利用火炮次口径发射实验技术,开展了头部刻槽结构弹体与传统尖卵形头部结构的弹体高速侵彻C80 钢混靶侵彻能力的实验研究.结果表明:2 种结构弹体以1 000m/s速度正侵彻3m的C80 钢混靶时,花瓣形头部刻槽弹体相比于尖卵形头部弹体具有更高的截面比动能,因此头部刻槽弹体侵彻余速提升4.49%～11.67%;弹体头部刻槽降低了混凝土碎块对弹体头部的摩擦作用力,导致头部刻槽结构弹体质量损失率为2.61%～2.00%,小于尖卵形头部结构弹体的质量损失率3.19%～3.79%.
Abstract
The present paper puts forward a new petal shaped grooved-nose of projectile.Experimental study on the penetration of petal shaped grooved-nose projectile and ogive-nose projectile,based on the experimental method of high-velocity impact fired by artillery and the launch technique of subcaliber projectile.The experimental results show that when the two structural projectiles are penetrating the 3 m C80 steel mixed target at a velocity of 1 000 m/s,the petal-shaped slotted projectiles have higher section specific kinetic energy than those with pointed oval heads,so the penetration velocities of the head-slotted projectiles are increased by 4.49%～11.67%.The head grooving reduces the friction force of concrete fragments on the head of the body,resulting in the mass loss rate of the head grooving structure of the body 2.61%～2.00%,which is lower than that of the pointed oval head structure of the body 3.19%～3.79%.
