| 摘 要： | 用燃速测试、DSC实验、发动机羽焰测定和红外热像仪,对比研究了在硝胺改性双基推进剂配方中加入含能亚硝酸复合钾盐(KE)和K2SO4,对推进剂燃烧性能、热分解特性和发动机羽焰的影响,并初步探讨了其影响机理。结果表明,与K2SO4相比,KE能够促进NC/NG双基组分和RDX的热分解,降低推进剂热分解放热量的程度较小,对推进剂燃烧性能的影响较小,且抑制硝胺改性双基推进剂二次燃烧的效果也较好。

| Abstract: | The influence on the performance of nitramine modified double base propellant with KE(a nitrite) and K2SO4 as eliminated-flame additive was investigated.By using burning rate test, differential scanning calorimetry(DSC), rocket engine test and an infrared thermal imaging device, the influence mechanism was discussed.Results show that the KE has the fewer influence on the heat of thermal decomposition and combustion characteristics, and better effect on suppression after burning of propellants than K2SO4.In addition, thermal decomposition characteristics of NC/NG and RDX in propellants are affecteded obviously by KE. |

| Keywords: | physical chemistry eliminated-flame additive nitramine modified double base propellant low signature combustion performance thermal decomposition |
