摘要
为评价新的氧化高氮杂环羟铵盐作为复合固体推进剂组分的能量潜力,采用推进剂性能评估程序PEP模拟计算了3,3'-二硝基-5,5'-联-(1-氧-1,2,4-三唑)二羟铵(DHDNBT)、5,5'-联-1,1'-二氧-四唑二羟铵(TKX-50)和5,5'-偶氮联-(1-氧四唑)二羟铵(DHABT)取代AP/Al/HTPB和AP/Al/GAP+NE两种复合固体推进剂体系中AP后的能量效果,并与HMX进行了比较。结果显示,在高固体含量的AP/Al/HTPB体系中,TKX-50和DHABT取代部分AP所得到的配方在很大的配方调节范围内能量性能与HMX取代AP配方相当,DHDNBT取代AP所得配方能量特性与同样含量HMX取代AP所得配方相当。在AP/Al/GAP+NE体系中,DHDNBT配方能量性能与同样含量HMX配方相同。含TKX-50和DHABT配方能量性能优于含HMX配方。含TKX-50和DHABT配方最高冻结流比冲分别为2662.7 N·s·kg-1和2696.0 N·s·kg-1,比HMX取代同体系中AP所得配方的最高冻结流比冲(2622.5N·s·kg-1)高40.2 N·s·kg-1(TKX-50)和73.5 N·s·kg-1(DHABT)。用设想的双-(1-氧-四唑)胺二羟铵(DHBTA)取代AP/Al/GAP+NE体系中AP可使最高冻结流比冲达到2708.7 N·s·kg-1,比HMX取代同体系中AP所得的最高冻结流比冲高86.2 N·s·kg-1,且在很大配方调节范围内有比HMX配方更高的能量特性。
To evaluate the energy potential of new oxidation high nitrogen heterocycle hydroxylammonium salts as composite solid propellant components,the energy effects after replacing AP in two kinds of composite solid propellant systems AP / Al / HTPB and AP / Al / GAP＋NE with dihydroxylammonium 5,5＇-bistetrazole-1,1＇-diolate（ TKX-50）,dihydroxylammonium 3,3＇-dinitro-bis-（ 1,2,4-triazole）-1,1＇-diolate（ DHDNBT） and dihydroxylammonium 5,5＇-azo-bis（ 1-oxidotetrazolate）（ DHABT） were calculated by using propellant performance evaluation program（ PEP） and was compared with HMX. Results show that in the high solid content AP / Al / HTPB system,the energy characteristics of the formula obtained by partly replacing AP with TKX-50 AND DHABT in a wide formula range are equivalent to those of the formula obtained by replacing AP with HMX. The energy characteristics of the formula obtained by replacing AP with DHDNBT are equivalent to those of the formula obtained by replacing AP with the same content HMX. In AP / Al / GAP＋NE system,the energy characteristics of the formula with DHDNBT are the same with those of the formula with HMX,but the energy performances of the formula with TKX-50 and DHABT are better than those of formula with HMX. The highest freezing specific impulse of the formula with TKX-50 and DHABT are 2662. 7 N·s·kg-1（ TKX-50） and 2696. 0 N·s·kg-1（ DHABT） respectively and 40. 2 N·s·kg-1（ TKX-50） and 73. 5 N·s·kg-1（ DHABT） higher than the highest freezing specific impulse of the formula obtained by replacing AP in the same system with HMX（ 2622. 5 N·s·kg-1）. Replacing AP in AP/Al / GAP＋NE with the assumed dihydoxylammonium bis（ oxidotetrazol-5-yl） amine（ DHBTA） can make the highest freezing specific impulse achieve 2708. 7 N·s·kg-1,86. 2 N·s·kg-1higher than the highest freezing specific impulse obtained by replacing AP in the same system with HMX and in a wide range of adjustment formula has a higher energy characteristics than HMX formula.
