破甲弹(High Explosive Anti-TankProjectile,HEAT)和穿甲弹(本刊下期将要谈及)是击毁装甲目标的两种最有效的弹种。穿甲弹靠弹丸或弹芯的动能来击穿装甲,因此,只有高初速火炮才适于配用。而破甲弹是靠成型装药的聚能效应压垮药型罩,形成一束高速金属射流来击穿装甲,不要求弹丸必须具有很高的弹着速度。因而,破甲弹能够广泛应用在各种加农炮、无坐力炮、坦克炮以及反坦克导弹上。在一般情况下,“破甲弹”是指成型装药破甲弹,也称空心装药破甲弹或聚能装药破甲弹。
The High Explosive Anti-Tank Projectile (HEAT) and Armor Armor (to be discussed later in this issue) are the two most effective bullets to destroy an armored target. The armor piercing armor is based on the kinetic energy of the projectile or the projectile, so that only high-speed guns are suitable for use. The armor-piercing bullet relies on the effect of the shaped charge to crush the drug-type cover and form a bunch of high-speed metal jets to penetrate the armor. The projectile does not require that the projectile must have a high playing speed. Thus, armor shells can be widely used in a variety of cannon, recoilless guns, tank guns and anti-tank missiles. Under normal circumstances, the “armor-piercing bullet” refers to the formation of charge-loaded armor-piercing bullets, also known as hollow charge d’affaires shells or poly charge-loaded armor-piercing shells.
