| 摘 要： | 运用最小自由能原理,设计了KNO3/C6H5NO3/NC体系烟火药配方。从热分解过程、感度、燃烧性能对比等方面探讨了新型药剂代替黑火药使用的可行性。与黑火药相比,对硝基苯酚点火药的机械、静电感度降低,增加了制造和使用过程的安全性,燃烧热增加57%,作功能力提高40%,改善了其燃烧热力学性能,在中心传火管中作为主装药使用时,膛内负压差降至-20MPa,提高了内弹道性能的一致性和发射安全性。

| Abstract: | The equilibrium states of KNO3/C6H5NO3/NC composition were calculated in least free-energy principle. The feasibility of new igniting charge substituting for black powder were disscussed from decomposition process,sensitivity and combustion property. Compared with black powder,impact,friction and electrostatic sensitivities of KNO3/C6H5NO3/NC composition decreased obviously. Combustion heat and working capabilities were increased by about 57% and 40%,respectively. Its use in central tube ignition system show that the peak value of in-bore pressure wave is about -20 MPa,and the interior ballistic properties are improved evidently. |
