钝感GAP微烟推进剂的能量性能计算

摘要

根据推进剂配方理论计算程序计算了含N-脒基脲二硝酰胺(FOX-12)、1,1-二氨基-2,2-二硝基乙烯(FOX、7)、3-硝基-1,2,4-三唑-5-酮(NTO)、三氨基三硝基苯(TATB)、3,4-二硝基呋咱基氧化呋咱(DNTF)、黑索今(RDX)、二硝酰胺铵(ADN)等高能钝感氧化剂及1,2,4-丁三醇三硝酸酯(BTTN)、二缩三乙二醇二硝酸酯(TEGDN)、三羟甲基乙烷三硝酸酯(TMETN)、N-丁基-2-硝酸酯乙基硝胺(Bu-NENA)等钝感增塑剂的几种单元推进剂和钝感微烟推进剂的能量性能.计算结果表明,所列的7种含能氧化剂中,由RDX和DNTF形成的单元推进剂的标准理论比冲分别为2 696.4 N·s/kg和2 610.2 N·s/kg,明显优于其他几种氧化剂.当采用DNTF部分取代GAP推进剂中的RDX或ADN后,推进剂的理论比冲、密度和特征速度相应提高.由于DNTF的感度低于RDX,因此DNTF引入推进剂中,对提高钝感GAP微烟推进剂的能量性能是有益的.%The energy characteristics of monopropellants and insensitive minimum smoke GAP propellants containing seven kinds of insensitive oxidizers and three insensitive energetic plasticizers, such as N-guanylureadinitramide( FOX-12) ,1,1-diamino-2,2-dinitroethylene ( FOX-7 ) , 3-nitro-1, 2,4-triazole-5-ketone ( NTO), triaminotrinitrobenzene (TATB) , 3,4-dinitrofurazanfuroxan (DNTF) , cyclotr imethylene trinitramine ( RDX), ammonium dinitramide ( AND ) , 1,2,4-butantriol trinitrate ( BTTN), triethylene glycol dinitrate(TEGDN) .trimethylolethane trinitrate(TMETN) and N-buty1-2-nitrate ethyl nitramine(Bu-NENA) were calculated by propellant energy calculation program. The calculation results show that the standard theoretical specific impulse(/sp) of mono-propellant containing DNTF and RDX are 2 6%.4 N · s/kg and 2 610. 2 N · s/kg respectively,which are superior to that of the other oxidizers above. After the GAP binder/DNTF/RDX/AND/Al propellant formulation is determined,the /sp.characteristic ve-locity(C· ) and density(p) gradually increase with the increasing content of DNTF. Therefore,introducing DNTF into propellant helps to improve the energy characteristics of the insensitive and minimum smoke GAP propellant.
