Detonation driving energy release characteristics of laminated composite charge of DNTF-based aluminized explosivesbased on cylinder tests

  • 摘要: 为探究叠层复合装药的爆轰释能规律,采用爆速差为1.85 km/s的3,4-二硝基呋咱基氧化呋咱(DNTF)基高爆速炸药与高爆热炸药制备成等厚度的叠层复合装药,通过狭缝扫描试验和圆筒试验分别获得了装药内的爆速变化和产物的膨胀释能曲线,并结合2种炸药爆轰产物的相互作用过程,分析了叠层复合装药与单一装药释能过程的主要差异。结果表明:爆轰波交替传播时,2种炸药均能迅速进入稳定爆轰状态;产物膨胀时,2种炸药的相互作用使装药爆轰驱动能量的分布特征发生显著变化,高爆速炸药的加载区域扩大,导致铜管速度降低,比动能较单一装药下降了6.7%,而高爆热炸药的加载区域缩小,铜管速度升高,比动能较单一装药提升了14.1%;此外,高爆热炸药爆轰产物处于压缩状态,有利于提升铝粉的反应速率,有望进一步增强叠层复合装药的驱动做功能力。
