摘要:

为研究不同黏结剂体系下HMX基温压炸药的爆炸释能特性,选择2种具有相似配方的HMX基温压炸药进行爆热、爆速、爆轰驱动性能、内爆炸性能等测试,分析了黏结剂的差异对温压炸药中铝粉反应速率、爆炸能量释放过程的影响。结果表明,不同黏结剂体系下温压炸药中铝粉的反应及释能过程有较大差异。其中,热固型浇注炸药的铝粉反应速率快于热塑型浇注温压炸药,热塑型浇注温压炸药参与有氧燃烧的铝粉较热固型浇注温压炸药多,其热作用转换的膨胀机械能弥补了冲击波转换机械能的不足。本研究为相关战斗部的装药选型、毁伤性能预估等提供依据或支撑。

Abstract:

The explosive energy release characteristics of thermobaric explosives with different binder systems during detonation are studies.Two types of HMX-based thermobaric explosives with similar formulations are selected for testing of detonation heat,detonation velocity,detonation driving performance,and internal explosion performance.In addition,the influence of differences in the binders on the reaction rate of aluminum powder and the release process of explosive energy in thermobaric explosives is analyzed.The results indicate that the aluminum powders in thermobaric explosives with different binder systems show significant differences in the reaction and energy release processes.Among them,the reaction rate of aluminum powder in thermosetting casting thermobaric explosives is faster than that of aluminum powder in thermoplastic casting thermobaric explosives.Moreover,the aluminum powder involved in aerobic combustion of thermoplastic casting thermobaric explosives is more than that involved in aerobic combustion of thermosetting casting thermobaric explosives,resulting in the expansion mechanical energy converted by its thermal effect compensating for the insufficient mechanical energy converted by shock waves.In summary,this research provides experimental evidence and support for the selection of charges and the estimation of destructive performance for the relevant warheads.
