Air blast performance of RDX-based aluminum fiber explosive

  • 摘要: 将铝纤维炸药与传统铝粉炸药和RDX炸药进行空中爆炸实验并得到压力时程曲线,经过分析计算得到3种炸药的压力峰值、二次击波、正相持续时间以及冲量。结果表明:铝纤维炸药的压力峰值相对于RDX没有明显提高,但其压力时程曲线衰减速度慢于RDX的,使铝纤维炸药的正相持续时间大于RDX,铝纤维炸药的冲击波冲量相对于RDX的平均提高了18%,与铝粉炸药的相当。铝纤维炸药的二次击波超压幅值与到达时间与铝粉炸药的接近,而铝纤维炸药的二次击波到达时间早于RDX,说明二次击波的超压幅值与到达时间与炸药类型有关。
