摘要:
为研究真空环境下铝粉含量对HMX基含铝炸药爆炸反应机制的影响,利用密闭爆炸罐测量了铝质量分数为15%(OA1)、20%(OA2)、25%(OA3)和30%(OA4)4种含铝炸药的爆炸场压力与温度,并采集分析了炸药爆炸气体产物。结果表明,4种含铝炸药的准静态压力大小依次为OA2 > OA1 > OA3 > OA4,炸药OA2爆炸威力最大;爆炸场平衡温度高低依次为OA4 > OA3 > OA2 > OA1,表明平衡温度随炸药中铝粉含量的增大而升高;首次峰值温度高低依次为OA1 > OA2 > OA3 > OA4,炸药OA1和OA2到达首峰温度值的时间远快于炸药OA3和OA4,除炸药OA1外其余3种炸药均有二次峰值出现,说明含铝质量分数15%和20%的炸药中部分铝粉提前反应;铝粉反应率大小依次为OA1 > OA2 > OA3 > OA4,表明随铝粉含量的增加,铝粉反应完全性降低。
Abstract:
To investigate the effect of Al powder content on the explosion reaction mechanism of HMX based aluminized explosive in vacuum environment, the explosion field pressure and temperature of four kinds of aluminized explosives of aluminum mass fraction as 15%(OA1), 20%(OA2), 25%(OA3) and 30%(OA4) were measured in a sealed explosion chamber, and explosion gas products of explosive were collected and analyzed. The results show that the quasi-static pressure value decreases in the order of OA2 > OA1 > OA3 > OA4, meaning that explosive OA2 has the greatest explosion power. The equilibrium temperature of explosion field decreases in the order of OA4 > OA3 > OA2 > OA1, indicating that the equilibrium temperature increases with the increase of aluminum content in the explosive. The first peak temperature of the four explosivesase decreases in the order of OA1 > OA2 > OA3 > OA4. For the time required to the first peak temperature, explosive OA1 and OA2 are far faster than explosive OA3 and OA4. Except explosive OA1, other three explosives appear the secondary peak. The part of aluminum in the explosive of aluminum mass fraction as 15% and 20% are reacted in advance. The reaction ratio of Al powder decreases in the orde of OA1 > OA2 > OA3 > OA4, indicating that with the increase of aluminum powder content, the completeness of Al powder reaction decreases.
