摘要
温压炸药中铝粉含量与粒径直接影响爆炸能量输出结构,特别是对温压炸药特有的“后燃效应”产生重大影响,进而对“温压效应”的形成起到至关重要的作用。研究介绍了铝粉含量与粒径对温压炸药的爆炸能量、压力效应、热毁伤效应和窒息效应的影响作用,分析了铝粉对后燃反应的影响机理,指出了温压炸药中添加铝粉的最佳含量与粒径范围。展望了未来的研究方向:应重点关注铝粉能量释放过程的反应动力学机制,开发与之适配的测试方法,深入解析温压炸药的能量释放过程,为其配方设计和能量输出结构的精准调控提供依据。
The content and particle size of aluminum powder in thermobaric explosives(TBXs)directly influence the energy output structure of explosions,significantly affecting the characteristic“post-combustion effect”of TBXs,which is crucial to the formation of the“thermobaric effect.”This paper discusses the influence of aluminum powder content and particle size on the explosive energy,pressure effect,thermal damage effect,and asphyxiation effect of TBXs.It also analyzes the mechanism by which aluminum influences the post-combustion reaction,identifying the optimal content and particle size range for aluminum addition in TBXs.Looking ahead,future research should focus on the reaction kinetics of energy release from aluminum powder,develop corresponding testing methods,and thoroughly analyze the energy release process of TBXs,providing a foundation for the precise control of formulation design and energy output structure.
