Sprengal type explosive

Based on the one-dimensional energy criterion of explosives shock initiation,considering the shock propagation of projectile impacting covered explosives,the relation formula of threshold velocity is obtained as Vw≈0.

根据裸炸药的一维短脉冲冲击起爆能量判据,结合射弹撞击带盖板炸药的冲击波传播规律,获得了同尺寸钨射弹与钢射弹引爆带等厚度盖板装药的阈值速度关系式为Vw≈0。
