Abstract

The ignition behavior of the polytetrafluoroethylene/aluminum/tungsten reactive projectile impacting a fuel-filled tank is experimentally investigated. In ballistic experiments, the reactive projectiles and the steel projectiles are launched from a smooth bore powder gun barrel to impact fuel-filled tanks at different velocities. The processes are recorded by a high-speed video camera. The result of the ignition-enhanced behavior of the reactive projectile relative to the steel projectile is presented. When the reactive projectile impacts the fuel-filled tank, the combined effects of the kinetic energy impact and the chemical energy release are achieved to improve the ignition probability. Especially, the flame (ignition kernel of the fuel) caused by the reactive projectile has a longer duration and a greater expansion region.

反应性弹丸撞击引起的燃油箱点火效应

摘要

实验研究了聚四氟乙烯/铝/钨反应弹丸撞击燃油箱的点火行为。在弹道实验中，反应弹和钢弹从光膛火药枪管发射，以不同的速度撞击装有燃料的坦克。这些过程由高速摄像机记录。给出了反应弹丸相对于钢弹丸的点火增强行为的结果。当反应弹撞击燃油箱时，实现动能撞击和化学能释放的综合作用，提高着火概率。特别是反应弹引起的火焰（燃料的点火核）持续时间更长，膨胀区域更大。
