含1,1-二氨基-2,2-二硝基乙烯(FOX-7)的钝感微烟推进剂能量参数和燃烧特性

Energy Parameters and Combustion Characteristics of the Insensitive and Minimum Smoke Propellants Containing FOX-7

研究了1,1-二氨基-2,2-二硝基乙烯(FOX-7)与改性双基推进剂主要组分的相容性以及含FOX-7的钝感微烟推进剂的能量参数和燃烧特性。结果表明,FOX-7与改性双基推进剂的主要组分具有良好的相容性;用FOX-7逐渐取代等质量比的NC和TMETN,钝感微烟推进剂的理论比冲提高,再用部分RDX取代FOX-7,推进剂的能量还可提高;含FOX-7的钝感微烟推进剂压力指数较高,某些铅盐催化剂可提高该类推进剂的燃速,但能否降低压力指数,与所用催化剂的品种密切相关。

The compatibility of 1,1-diamino-2, 2-dinitroethylene （FOX-7） with some important components of composite modified double base （CMDB） propellant and energy parameters and combustion characteristics of the insensitive and minimum smoke propellants containing FOX-7 were studied. The results show that the binary systems of FOX-7 with the main components of CMDB propellant have good compatibility. The theoretical specific impulse of the propellants increase with the mass fraction of gradually substituting NC and TMETN with FOX-7 in an equal mass ratio. The energy of the propellant increase more when FOX-7 is replaced with RDX. The pressure exponent of the insensitive and minimum smoke propellants containing FOX-7 is high. Some lead salts can increase the burning rates of the propellants, but their abilities of reducing the pressure exponent have a relation with used catalyst kind.
