硝胺发射药热分解中间产物对燃烧的影响

Effects of Nitramine Propellant Primary Decomposition Products on Combustion

研究了高压下硝胺发射药热分解中间产物对燃烧性能的影响。通过对热分解产物的分析和密闭爆发器试验结果表明:NO_2在高压下对黑索今(RDX)的爆燃有抑制作用,可缓和燃速-压力曲线转折的现象,并降低了硝胺发射药的燃速压力指数。而醛类中间产物则起相反的作用。这一研究结果可为研究硝胺发射药的配方和缓解u—p曲线转折具有理论意义与实用价值。

This paper studies effects of nitramine propellant primary de-composition products on combustion at high pressure analysis and experimentshow that NO_2 can inhibit the deflagration of RDX, elliminate the flunctua-tion phenomena of the burning velocity versus pressure curve,and decrease thepressure exponent of nitramine propellant, But the aldehyde has the inversefunction. This study will be useful for futher composition studies of nitraminepropellant and it is of theoretical and practical value to sohe the problem ofu-p curve fluctuation.
