活性弹丸对混凝土靶的毁伤效应实验研究

设计并制备了由活性材料内核（PTFE/AL）、高强度钢外壳组成的活性弹丸,基于25 mm口径弹道炮发射平台进行了该弹丸对混凝土靶的毁伤效应实验.实验结果表明：在941~1 679 m/s着速下,活性弹丸撞击混凝土靶后均发生了剧烈爆燃反应.从混凝土成坑效应结果可以看出,活性弹丸毁伤效果比同规格惰性材料内核（PTFE）弹丸有大幅提高.活性弹丸依靠自身动能与强度侵入混凝土靶体,侵入过程中活性材料内核在靶体内部爆炸并释放大量化学能,这种“侵爆耦合效应”是造成混凝土靶高效毁伤的主控机制.

Experimental Research on the Damage Effect of Concrete Target Impacted by Reactive Projectile

An reactive projectile filled with reactive core (PTFE/AL) and high-intensity shell was designed and prepared. Experiments on the damage effect of concrete target impacted by reactive projectile were conducted base on the 25 mm ballistic gun launching platform. It demonstrates that reactive projectiles at 941~1 679 m/s all burn and explode violently after impacting concrete targets. The crater effect of the concrete targets shows that damage efficiency of the active projectiles will be improved greatly compared with that of the same size inert material core projectiles. Reactive projectiles penetration into the concrete targets relys on its own kinetic energy and strength, meanwhile, reactive material cores explode violently and release a great deal of chemical energy during the penetration progress in the targets, this "penetration explosion coupling effect" is the dominant mechanism causing highly efficient damage of concrete targets.
