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。
In order to study the effects of energetic oxidant cyclic triphenylenetetramine (RDX), hexanitrohexaazaisowurtzitane (CL-20), ammonium dinitramide (ADN) and nitrofurazone (HNF) After the ammonium borate (AP) composite propellant energy characteristics and characteristics of the signal performance, using the principle of minimum free energy formula for chemical equilibrium performance calculations. The results showed that the four high-energy oxidants gradually replaced AP to achieve the goal of increasing the specific impulse of standard theory and reducing the second-order smoke. The peak values of standard impulse rate increase were 0.85%, 1.1%, 3.37% and 5.1%, respectively. ADN Reduce the characteristics of the signal secondary combustion flame best. ADN and HNF gradually replace Al, the standard theory of specific impulse, a smoke and secondary combustion flame showed a downward trend, the second smoke showed a rising trend.
