摘要:次口径穿甲弹拥有双弹头,外层弹头为传统类口径弹头,体积占全弹的 60%左右,内 置一枚细长型弹芯(次口径弹头),以穿透内部装甲,虽然外弹头仍然留在装甲上,然而 装甲实际上已经遭受到毁灭性打击了。
现在,国内一些火炮设计方面的工作者想到是不是可以利用次口径穿甲弹发射的原 理来提升炮弹射速,我们知道火炮口径越大,炮弹的射程将越远,在这其中弹体的旋转 稳定性将起很大作用。随着深侵彻武器的发展,与之配套的次口径发射试验技术也因此 受到关注。自 20 世纪 90 年代以来,火炮工作者们甚至实现了用火炮发射步枪子弹。

Title Experimental Technique of Sub-caliber Launch
Abstract:Sub-caliber armor piercing bullet has two warheads,the outer warhead is a conventional caliber warhead,the volume has accounted for the entire armor piercing bullet’s 60% , the interior has a more sharp inner warhead (sub caliber warhead) to penetrate the interior of the outer warhead has not penetrated the armor,although the outer warheads remain on the armor, the armor has actually been dealt a devastating blow.
Now, some domestic workers in the aspects of gun design thought whether it can be improved the rate of fire shells by using the principle of sub caliber projectile launch,we know that the larger the caliber of the gun, the further the range of the projectile, in which the rotation stability of the body will play a significant role.With the development of the deep penetration weapon, the secondary emission test technology is also concerned.Since 1990s, artillery workers have even achieved the use of artillery firing rifle bullets
