为了研究丁基-硝氧乙基硝胺(Bu-NENA)对NC基推进剂能量及燃烧性能的影响,通过俄罗斯Real软件计算了Bu-NENA对推进剂的能量性能的影响;通过吸收-压延的方法制备了推进剂样品,测试了推进剂的密度、爆热、比容、点火延迟、燃速,计算了压强指数;通过燃烧波、火焰照片以及熄火表面探讨了Bu-NENA对推进剂燃烧性能影响的机理。结果表明,在NC基推进剂中Bu-NENA替代NG使能量下降,但是产气量增加,使推进剂的燃速大幅度下降,2MPa下燃速降幅75%以上,20MPa下燃速降幅64%以上;压强指数提升,NC/NG基推进剂用部分催化剂可能对NC/Bu-NENA基体系失效;推进剂的点火延迟时间增加;推进剂的燃速大幅度降低的原因可能是因为Bu-NENA在燃烧时挥发吸热以及燃温降低带来的热反馈降低。 |

In order to investigate the influence of N-butyl-N-nitratoethylnitramine(Bu-NENA)on the energy and combustion properties of NC based propellants,energy properties was theoretically calculated by Russian Real software.The propellant samples were prepared by the method of absorption-extrusion technique.The density,detonation heat,specific volume,ignition delay time,burning rate were tested and the pressure exponent were calculated.The mechanism of the influence of Bu-NENA on the combustion performance of the propellant was analyzed by combustion waves,flame photographs and morphology of flameout surface.The results showed that the replacement of NG by Bu-NENA in NC based propellant reduces energy but increases gas production.The burning rate of propellants can be significantly reduced,with the decrease of more than 75%for 2MPa and the decrease of more than 64%for 20MPa.The pressure exponent was increased.Some catalysts used for NC/NG based propellants may fail in NC/Bu-NENA based system.The propellant ignition delay time is increased.The burning rate of the propellant is greatly reduced because of the volatilization of Bu-NENA during combustion and the decrease of thermal feedback caused by the decrease of combustion temperature. |
