Abstract

A reactive core filled tungsten alloy projectile structure was proposed to improve the igniting effects of traditional inert projectile on diesel oil tank. With the combination of impacting tests by 12.7 mm caliber ballistic gun and theoretical analysis on the dynamic penetrating process, effects of the projectile structure and impacting position on the tank on the igniting effects were obtained, while the igniting mechanism was revealed. The results indicate that under the condition of filling the same amount of reactive materials, a lower length to diameter ratio of the reactive material cavity and a higher length to diameter ratio of the solid segment result in more complete non self-sustainable reaction of the reactive filling, more prominent hydrodynamic effect, and higher ignition efficiency. By affecting the hydrodynamic effect and igniting duration, impacting positions on the oil tank obviously decide the igniting results. By combining the hydrodynamic effects and chemical energy release, reactive core filled projectile structures demonstrate higher ignition efficiency than traditional inert projectiles.
