利用国军标方法及CAD系统软件,在标准条件(pc∶p0=70∶1)下,计算了含1,1-二氨基-2,2-二硝基乙烯(FOX-7)的各类推进剂的能量特性参数,分析了氧化剂(AP、RDX、CL-20)及黏合剂(HTPB、PET、GAP、PBAMO)等成分对FOX-7推进剂能量特性的影响。结果表明,将AP加入HTPB/FOX-7推进剂配方中取代FOX-7可有效改善氧条件,有利于推进剂能量的提高。在黏合剂含量较低(质量分数<8%)的推进剂体系中,使用惰性黏合剂有利于提高推进剂的能量;而在黏合剂含量较高(质量分数>10%)的推进剂体系中,使用含能黏合剂提高推进剂能量的幅度优于惰性黏合剂,且GAP优于PBAMO。用FOX-7取代NEPE推进剂中的AP,推进剂最大理论比冲可达2 567 N.s/kg。由GAP/FOX-7/RDX组成的无烟推进剂,在很宽的范围内都可以达到2 400 N.s/kg以上的理论比冲值。
Using the national military standard method and CAD system software, under the standard conditions (pc: p0 = 70: 1), calculated the 1,1-diamino-2,2- dinitro ethylene (FOX-7) The energy characteristics of propellant were studied. The effects of oxidant (AP, RDX, CL-20) and binders (HTPB, PET, GAP, PBAMO) on energy characteristics of FOX-7 propellant were analyzed. The results showed that adding AP into the formulation of HTPB / FOX-7 propellant to replace FOX-7 can effectively improve the oxygen conditions and promote the improvement of propellant energy. In the low binder content (<8%) propellant system, the use of inert binder is beneficial to improve the energy of propellant; while in the binder system with higher binder content (> 10%) , The use of energetic binders to improve propellant energy is superior to that of inert binders and GAP is superior to PBAMO. With FOX-7 instead of AP in NEPE propellant, the maximum theoretical specific impulse of propellant is up to 2 567 N · s / kg. Smokeless propellants consisting of GAP / FOX-7 / RDX achieve a theoretical specific knock of over 2,400 N · s / kg over a wide range of temperatures.
