利用能量计算程序计算了N,N′-二硝基哌嗪(DNPZ)、N-脒基脲二硝酰胺(FOX-12)、1,1-二氨基-2,2-二硝基乙烯(FOX-7)、钝感黑索今(I-RDX)、2,6-二氨基-3,5-二硝基吡嗪-1-氧化物(LLM-105)、硝基胍(NQ)和1,4,5,8-四硝基-1,4,5,8-四氮杂萘烷(TTNZ)7种钝感化合物的单元推进剂及用于钝感低特征信号推进剂的能量特性。结果表明:所列的7种含能化合物中,由I-RDX、FOX-7和TTNZ形成的单元推进剂、复合改性双基推进剂及聚叠氮缩水甘油醚(GAP)基推进剂的各能量特性的综合效果均较优,随着这3种钝感含能添加剂质量分数增加,形成的双基系推进剂的理论比冲、特征速度、燃烧温度和等容爆热逐渐升高,而氧系数和燃烧产物的平均相对分子质量逐渐降低。

The energy characteristics of monopropellants and propellants with insensitive and minimum signature properties containing seven kinds of insensitivity materials, such as N, N＇-dinitropiperazine （DNPZ） , N-guanylureadinitramide （ FOX-12 ）, 1,1 -diamine-2,2-dinitroethylene （ FOX-7 ）, insensitivity RDX （ I-RDX）, 2,6-diamino-3,5-dinitropyrazine-1 -oxide （ LLM-105 ）, nitrognanidine （NQ） and 1.4,5,8-tetranitro-1,4,5,8-tetraazadecalin （TTNZ）, are calculated by propellant energy calculation program. The calculation results show that the integrated energy characteristics of monopropellant, composite modified double base propellant and glycidyl azide polymer （GAP） base propellant containing I-RDX, FOX-7 and TTNZ respectively are excellent among seven materials above. The energetic properties of composite modified double base propellant containing I-RDX, FOX-7 and TTNZ, such as specific impulse, characteristic velocity, combustion temperature and heat of explosion at constant volume, increase with the mass fraction of the energetic additives increasing, while the oxygen coefficient and the relative molecular mass of products decrease with the mass fraction of three energetic additives increasing.
