摘要
为了揭示2,4-二硝基茴香醚(DNAN)基高能钝感熔铸炸药的爆轰传播特性,加快DNAN基熔铸炸药的工程化应用,采用连续导线法测量了DNAN基含铝熔铸炸药的临界直径。结果表明:Al含量(质量百分比0~30%)增大、Al粒度d_(50)(分别为6μm、12μm、31μm)减小均会降低爆轰传播的临界直径;黑索今(RDX)的粒度d_(50)(分别为19μm、147μm、751μm)增大、RDX品质提高会增大爆轰传播的临界直径。研究结果为DNAN基含铝熔铸炸药的配方和战斗部结构设计提供基础的技术参数。
In order to reveal the detonation propagation characteristics of DNAN （2,4-dinitroanisole）- based melt-cast explosives, and speed up the application of the explosives, the critical diameter of DNAN-based aluminized melt-cast explosives is measured by continuous wire method. The measured results demonstrate that the critical diameter of DNAN-based aluminized melt-cast explosives decreases with the increase in wt% of aluminum （0 - 30wt% ） and the decrease in particle sizes of both aluminum （ d50 ： 6 μm, 12μm, 31 μm） and RDX （d50：19μm, 147μm, 751μm） , and increases with the decrease in crystal quality of RDX. The investigation can provide a basic reference for both the formulation of DNAN- based aluminized melt-cast explosives and the warhead design.
