Al/AP对RDX基复合炸药水中爆炸参数的影响

以RDX为主炸药,通过添加不同含量的Al粉和AP制成6种RDX基复合炸药,采用水中爆炸实验研究,从冲击波参数和气泡参数等方面分析了Al粉和AP对复合炸药水中爆炸性能的影响。结果表明,主炸药含量不变时,随着Al与AP摩尔比的增大,冲击波峰值压力、时间常数、冲量和能流密度都逐渐减小,气泡周期、气泡能和最大气泡半径先增大后减小,当Al与AP的摩尔比为3.8左右时,达到最大值。

Influence of Al/AP on the Underwater Explosion Parameters of RDX-based Composite Explosives

The six kinds of composite explosives are formed by adding difference content of Al and AP based RDX as major explosive,and the underwater explosion experiment is done by these composite explosives.The influence of Al and AP on the underwater explosion parameters of composite explosives was analyzed from shock wave parameters and bubble parameters.The results show that when the major explosive content is fixed,the shock wave peak pressure,time constant,impulse and energy flux density all decrease with the Al/AP mole ratio increase,while the bubble period,bubble energy and the maximum bubble radius increase firstly,when Al/AP mole ratio is 3.8,these values achieve maximum,then decrease with Al/AP mole ratio increase.
