摘要/Abstract

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d₅₀（分别为6 μm、12 μm、31 μm）减小均会降低爆轰传播的临界直径；黑索今（RDX）的粒度d₅₀（分别为19 μm、147 μm、751 μm）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。

Abstract: 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, 12 μm, 31 μm) and RDX (d₅₀:19 μm, 147 μm, 751 μm), 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. Key
