空气电弧等离子体作用下发射药的燃烧特性

为了研究发射药等离子体点火作用机理,用扫描电子显微镜研究了不同强度电弧放电等离子体揭示的3种制式发射药及新型ETPE发射药在等离子体作用后的燃烧表面变化规律,得到等离子体点火后发生燃烧反应的质量.结果表明,电弧等离子体输入电能对发射药的点火有着重要影响,随着输入电能的增加,参加反应的发射药质量逐渐增加.ETPE发射药燃烧表面与常规制式发射药燃烧表面有较大差别.发射药对电弧等离子体的相对敏感程度不同,双基发射药最强,ETPE发射药最弱.

Combustion Characteristics of Gun Propellant under the Arc Plasma in Air

In order to study the interaction mechanism between plasma and propellant,the change rules of the surfaces for three typical propellants and an ETPE propellant exposed to the arc plasma with different discharge intensity in air were studied with SEM.The mass of the propellant which took part in the reaction with plasma was obtained.The results show that the energy input of the arc plasma in air had a significant effect on the ignition of propellant.The mass of reacted propellant would increase with increasi...
