摘要
为深入研究硝胺改性双基推进剂的安全性能,根据GB14372-1993以及GJB772A-1997对黑索今（RDX）含量不同（18.0%~55.1%）的硝胺改性双基推进剂进行了雷管感度试验、冲击波感度试验、爆轰临界直径测定以及爆速测试,并与普通双基推进剂进行了对比。结果表明：随着推进剂中RDX的增加,推进剂的雷管感度、冲击波感度呈上升趋势,爆轰安全性呈下降趋势,爆速呈升高趋势。当RDX含量达到34%以上时,在-5℃下就可以被雷管直接引爆;当RDX含量达到55.1%时,推进剂的临界隔板厚度增加至33.5 mm,爆轰传播临界直径为8 mm,爆速超过8000 m·s^-1。
In order to study the effects of RDX on the safety performance of nitramine modified double base propellants（M DBP）,detonator sensitivity test,shock sensitivity test,detonation safety test and detonation velocity test were carried out respectively according to GB14372-1993 and GJB772A-1997 for nitramine modified MDBP samples with different content of RDX（18.0%~55.1%） and a common MDBP sample.Results show that with increasing of RDX content,the propellant has higher sensitivity to shock wave and detonator,lower detonation safety,and its detonation velocity of propellant increases.Detonator could explode the propellant at-5 ℃ directly when the content of RDX in propellant is 34%.The critical gap thickness is up to 33.5 mm,the propagation critical diameter of detonation 8 mm and the detonation velocity more than 8000 m · s^-1 when the content of RDX is 55.1%.
