无机氧化剂二硝酰基胺铵在固体推进剂中的能量性能分析

Analysis of energy performance of inorganic oxidizer ammonium di(nitramido)amine in solid propellants

为考察新型含能无机氧化剂二硝酰基胺铵(ADNA)对固体推进剂能量性能的贡献水平,采用编制的能量计算星程序5.0版,模拟计算了ADNA、ADN(二硝酰胺铵)及AP(高氯酸铵)对CMDB(复合改性双基)、HTPB(端羟基聚丁二烯)、NEPE(硝酸酯增塑聚醚)、GAP(聚叠氮缩水甘油醚)推进剂的能量贡献水平。结果表明:ADNA取代CMDB、HTPB、GAP、NEPE推进剂中的AP,都使体系标准理论比冲增加,羽流红外辐射性能降低;ADNA对推进剂的能量贡献要优于ADN,如果设计合适的HTPB、GAP配方体系,ADNA的能量贡献超越RDX。

In order to investigate the contribution level of the novel energetic inorganic oxidizer ammonium di(nitramido)amine(ADNA)to the energy performance of solid propellants,the energy contribution levels of ADNA,ADN(ammonium dinitramide)and AP(ammonium perchlorate)to the energies of the CMDB(composite modified double-base)propellant,HTPB(hydroxyl-terminated polybutadiene)propellant,NEPE(nitrate ester plasticized polyether)propellant and GAP(glycidyl azido polymer)propellant were simulated and calculated by using the compiled Energy Calculation Star Program Version 5.0.The results show that replacing AP in the CMDB,HTPB,GAP and NEPE propellants with ADNA increases the standard theoretical specific impulse of such systems,and decreases the infrared radiation performance of the plume.The contribution of ADNA to the energy of propellant is superior to that of ADN.If the suitable HTPB and GAP formulation systems are designed,the energy contribution of ADNA exceeds that of RDX.
