一、前言动能穿甲弹和空心装药破甲弹是两种基本形式的反装甲弹。动能穿甲弹是由高膛压炮以很高的速度发射的硬心弹,完全依靠动能穿甲。成形装药,经常叫做“空心装药”,是在一个炸药圓柱筒内嵌入一个铜药形罩圆锥体。当击中目标时,瞬发引信起爆高能炸药,高压爆轰波把药形罩挤压成一条以8公里╱秒的高速流动的射流。射流冲击装甲目标所产生的压力值比裝甲材料的屈服强度大一个数量级。因此,可以使用动液流来模拟穿甲过程。简单地说,射流作用在装甲钢上并迫使装甲钢流动,就象水流推动泥土一样。由于它的效能完全不取决于弹丸的速度,因此空
I. INTRODUCTION The kinetic energy armor piercing and hollow charge armor bullet shells are two basic types of anti-armor shells. Kinetic armor piercing is a hard bomblet fired by a high chamber gun at very high speeds, completely dependent on kinetic energy armor piercing. Formed charge, often referred to as “hollow charge,” is the insertion of a bronze cone cone into an explosive cylinder. Upon striking the target, the instantaneous fuse detonates the high-explosive, high-pressure detonation squeeze the escutcheon into a high velocity jet at 8 km / s. Jet impact armor target pressure generated value than the yield strength of armor material by an order of magnitude. Therefore, dynamic flow can be used to simulate the piercing process. Simply put, the jet acts on the armor and forces the armored steel to flow, just as the current pushes the soil. It is empty because its efficiency does not depend on the speed of the projectile at all
