FOX-7对CMDB固体推进剂性能的影响(英文)

Effect of 1,1-diamino-2,2-dintroethene( FOX-7) on properties of CMDB propellants

为有效降低高能CMDB推进剂体系的危险性,研究了1,1-二氨基-2,2-二硝基乙烯(FOX-7)在CMDB推进剂中的应用,采用感度仪、热像仪及DSC等测试分析了FOX-7对其感度、燃烧特性及热性能的影响。研究表明,FOX-7不但明显降低CMDB推进剂的感度(摩擦感度4%,撞击感度20.4 cm),大幅提高CMDB推进剂低压下的燃速(约提高39.49%),促进了CMDB推进剂的热分解,且保持了CMDB推进剂的高能量、低特征信号和较好的力学性能等优点。理论计算和实验表明,FOX-7可作为高能钝感含能组分在武器型号中推广应用。

In order to decrease the sensitivity of CMDB propellants, several propellant formulations containing 1,1-diamino-2,2- dinitroethene（FOX-7） were studied.The effects of FOX-7 on the sensitivity properties, combustion characteristics and thermoehemi- eal properties of the CMDB propellants were investigated by the impact sensitivity apparatus ,the thermal video systems and DSC in- strument, et al.It was found that FOX-7 not only decrease the sensitivity properties obviously （Impact sensitivity 20.4 cm, Friction sensitivity 4% ）, enhance the combustion characteristics at low pressure by 39.49 % and accelerate the decomposition of the CMDB propellants ,but also maintain the advantage of RDX/CMDB propellant for high energy, low signature and good mechanism proper- ties.It is indicated that FOX-7 can be used in weapon as high energetic and insensitive material by theoretical calculation and exper- iment.
