钝感GAP微烟推进剂的能量性能计算

Energy characteristics calculation of insensitive and minimum smoke GAP solid propellant

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）, eyclotr imethylene trinitramine （ RDX ）, ammonium dinitramide （ ADN ）, 1,2,4-butantriol trinitrate （ BT＇FN ）, 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 mono- propellant 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/A1 propellant formulation is determined, the Isp, characteristic velocity（ 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.
