钝感GAP微烟推进剂的能量性能计算

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。

Energy characteristics calculation of insensitive and minimum smoke GAP solid propellant

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(ADN),1,2,4-butantriol trinitrate(BTTN),triethylene glycol dinitrate(TEGDN),trimethylolethane trinitrate(TMETN) and N-butyl-2-nitrate ethyl nitramine(Bu-NENA) were calculated by propellant energy calculation program.The calculation results show that the standard theoretical specific impulse(Isp) of monopropellant containing DNTF and RDX are 2 696.4 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/ADN/Al propellant formulation is determined,the Isp,characteristic velocity(C*) and density(ρ) 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.
