【摘要】 利用能量计算程序计算了含富氮化合物2-硝亚胺基-5-硝基-六氢化-1,3,5-三嗪(NNHT)的改性双基(CMDB)推进剂的能量特性,并计算了用3种含能添加剂高氯酸铵(AP)、六硝基六氮杂异伍兹烷(CL-20)、黑索今(RDX)和2种增塑剂1,5-二叠氮基-3-硝基-3-氮杂戊烷(DIANP)及二缩三乙二醇二硝酸酯(TEGDN)分别部分取代NNHT和硝化甘油(NG)后,对含NNHT的改性双基推进剂能量特性的影响规律。结果表明:无论推进剂中是否含铝粉,用NNHT取代CMDB推进剂中的硝化棉(NC)和NG后,将不同程度地降低原推进剂的各能量特性参量;用CL-20部分取代NNHT后,可使NNHT-CMDB推进剂的理论比冲明显提高;用DIANP或TEGDN部分取代推进剂中的NG,各能量特性参量均随其含量增加而减小。更多还原

【Abstract】 The energy characteristics of the composite modified double base(CMDB) propellants containing 2-nitroimino-5-nitro-hexahydro-1,3,5-triazine(NNHT) were calculated by propellant energy calculation program. The three energetic additives of ammonium perchlorate(AP), hexanitrohexaazaisowurtzitane(CL-20), hexogen(RDX), and the two plasticizers of 1,5-diazido-3-nitrazapentane(DIANP) and triethyleneglycol dinitrate(TEGDN) were used as substitute of NNHT and nitroglocery(NG) in CMDB propellant formulations, and the effects of their content changes on the energy characteristics of NNHT-CMDB propellants were investigated. Our results indicated that the integrated energy characteristics of CMDB propellant will decrease to some extent with nitrocelluluse(NC) and NG of propellant are replaced by NNHT. The theoretical specific impulse of NNHT-CMDB propellant will increase greatly with AP or CL-20 are added into the propellant formulation. The energy characteristics will decrease with the increasing replacing content of DIANP or TEGDN for NG in the propellant.更多还原
