为考察新型含能化合物二硝基胍(DNGu)对固体推进剂能量性能的影响,采用能星5.0版程序,模拟计算了DNGu替换CMDB(复合改性双基)、HTPB(端羟基聚丁二烯)推进剂中的AP(高氯酸铵),替换NEPE(硝酸酯增塑剂聚醚)、GAP(聚叠氮缩水甘油醚)推进剂中的主氧化剂AP和次级氧化剂HMX(环四亚甲基四硝胺)后体系的能量效果。结果显示:DNGu单质推进剂平衡流比冲比ADN(二硝酰胺铵)、AP要高得多;DNGu对4种推进剂配方体系能量贡献均优于AP,如果设计合适的配方体系,DNGu对CMDB推进剂能量贡献超越ADN;DNGu作为GAP推进剂中主氧化剂时,能量水平高于AP,作为次级氧化剂时,能量水平低于HMX;DNGu作为NEPE推进剂主氧化剂时,理论比冲存在最大值,替换HMX作为次级氧化剂时,理论比冲降低。
In order to investigate the effect of DNGu on the energy performance of solid propellants, DNGu was used to simulate the effect of DNGu on CMDB (complex modified bitumen), HTPB Ene) AP (ammonium perchlorate) in the propellant, the main oxidant AP in the NEPE (nitrate plasticizer polyether), GAP (poly azide glycidyl ether) propellant and the secondary oxidant HMX Methylenetetramine) post-system energy effect. The results showed that the equilibrium flow ratio of DNGu elemental propellant was much higher than that of ADN (ammonium dinitramide) and AP. The contribution of DNGu to the four propellant formulations was better than that of AP. If a suitable formulation system was designed, The energy contribution of CMDB propellant exceeds that of ADN. When DNGu is the main oxidant in GAP propellant, its energy level is higher than that of AP, and its energy level is lower than that of HMX as secondary oxidant. When DNGu is the main oxidant of NEPE propellant, Value, replace the HMX as a secondary oxidant, the theoretical impulse reduction.
