摘 要:为研究含能氧化剂环三亚甲基三硝胺(RDX)、六硝基六氮杂异戊兹烷(CL-20)、二硝酰胺铵(ADN)、硝仿肼(HNF)逐步取代高氯酸铵(AP)后复合推进剂的能量特性和特征信号性能,采用最小自由能原理对配方进行了化学平衡性能计算。结果表明:四种高能氧化剂逐步取代AP都达到了增加标准理论比冲和降低二次烟的目的,标准理论比冲增加率的峰值分别为0.85%,1.1%,3.37%及5.1%,ADN对降低特征信号二次燃烧火焰效果最好。ADN和HNF逐步取代Al后,标准理论比冲、一次烟及二次燃烧火焰都呈下降趋势,二次烟呈上涨趋势。To study energetic characteristics and signature of composite propellant of Ammonium Per- chlorate (AP) using a substitute of oxidant, such as Cyclotrimethylenetrinitriamine (RDX), hexanitro- hexazaisowurtzitane( CL-20), Ammonium dinitramide ( ADN ) and Hydrazinenitroform ( HNF), theoretical performance of the propellant was calculated based on the principle of free-energy minimization. The results show that theoretical specific impulse of the composite propellant is increased and signature of secondary smokes is reduced,and the most increasing rate of theoretical specific impulse are 0.85% ,1.1% ,3.37% and 5.1% , respectively. Effects of secondary combustion of the composite propellant of AP using a substitute of ADN are decreased obviously. The energy properties are consistent with signature when the composite propellant of A1 is using a substitute of ADN and HNF. Theoretical specific impulse, primary smoke and secondary combustion of the composite propellant are all decreased.
