摘要:
为研究1,5-二叠氮基-3-硝基氮杂戊烷(DIANP)对发射药枪口焰的影响,以14.5 mm弹道枪为实验平台,采用高速摄影仪测试了不同DIANP含量的发射药枪口火焰参数;分析了DIANP含量及装药质量对枪口焰面积(A)、最大直径(C)、平均直径(Dmean)和积分光密度(IOD)的影响;分析了叠氮硝胺发射药枪口焰初始火焰、中间焰和二次焰的结构及持续过程。结果表明,在双基发射药中加入DIANP以后,火药力从1 170 kJ/kg增至1 189 kJ/kg,然后开始降低,发射药爆温基本呈线性降低;发射药爆温及燃烧气体产物组成共同影响枪口焰的形成,DIANP的加入增加了燃烧产物中可燃气体含量,但可以有效降低发射药的爆温;与无DIANP的双基发射药相比,添加DIANP可以降低发射药的枪口焰面积、最大直径、平均直径和积分光密度,当添加DIANP的质量分数为12.5%时,叠氮硝胺发射药样品无二次焰的产生,火焰持续时间为8 ms,比传统双基药降低71%。
Abstract:
To study the effect of 1,5-diazido-3-nitrazpent (DIANP) on the muzzle flash of gun propellant, taking 14.5 mm ballistic gun as the experimental platform, the muzzle flash parameters of gun propellant with different content of DIANP were measured by high speed camera. The effect of DIANP content and charge mass on the area(A), maximum diameter(C), average diameter(Dmean) and integral optical density(IOD) of the muzzle flash was analyzed. The structure and lasting process of primary, intermediate, secondary flash for the muzzle flash of azidonitramine gun propellan were analyzed. The results show that the impetus is increased from 1 170 kJ/kg to 1 189 kJ/kg and then decreases after the addition of DIANP in double-base gun propellant.The detonation temperature of gun propellant basically reveals a linear decrease. The detonation temperature and combustible gas composition together affect the formation of muzzle flash. With the addition of DIANP, the combustible gas content in combustion products increases but the detonation temperature of gun propellant effectively decreases. Compared with double-base gun propellant without DIANP, DIANP can reduce the area, maximum diameter, average diameter and integral optical density of the muzzle flash. As the mass fraction of DIANP is 12.5%, the azidonitramine gun propellant sample has no production of secondary flash and the flash duration time is only 8 ms,which is reduced by 71% compared with traditional double-base gun propellant.
