摘要/Abstract

摘要： 为研究具有高固含量(黑索金RDX质量分数为48.5%)改性双基推进剂的热危险性，采用热重分析仪TG、差示扫描量热仪DSC以及加速量热仪ARC，对比分析了双基推进剂S0，改性双基推进剂GHT-1A和单质炸药RDX的热分解特性，并从两个方面评估了GHT-1A的热危险性。TG/DSC实验结果显示GHT-1A中双基组分的分解峰温高于S0的分解峰温，而其炸药组分的分解峰温与单质炸药RDX接近。ARC的实验结果显示GHT-1A在理想绝热条件下的起始分解温度为138.9℃，绝热温升为1415.3℃，达到最大温升速率所需时间为13.8min，单位质量产生气体最大压力为13.1MPa·g-1。研究结果表明，GHT-1A发生热爆炸的可能性略低于双基推进剂S0，而高于单质炸药RDX，爆炸破坏性则较强。

Abstract: To study the thermal hazard of the composite modified double-base propellant with high solid content，the thermal decomposition of GHT-1A was studied by TG，DSC，and ARC. Its mass fraction of Hexogen (RDX) is about 48.5%. The test results were compared with one double-base propellant S0 and single-compound explosive RDX. And the thermal hazard of GHT-1A was evaluated from two aspects. The TG/DSC test results show that the decomposition peak temperature of double-base component of GHT-1A is higher than that of S0，and the peak temperature of explosive components of GHT-1A is close to that of single-compound explosive RDX. The ARC test results show that，in the ideal adiabatic environment，the initial exothermic temperature for GHT-1A is 138.9℃，the adiabatic temperature rise is 1415.3℃，the time to the maximum rate is 13.8min，and the maximum pressure produced by unit mass is 13.1MPa·g-1. The studies have revealed that，the explosion feasibility of GHT-1A is lower than that of double-base propellant S0，but higher than that of single-compound explosive RDX. And the destructive effect of GHT-1A is among the strongest.
