| 摘 要： | 在火炸药燃速预估模型的基础上，分析了硝胺单质炸药的热分解特征，提出了硝胺单元推进剂燃烧初期热分解机理的有关假说，并将气相分解产物分类为氧化剂、还原剂、可裂解自由基和惰性基团，进而提出了硝胺单元推进剂燃速和压力指数公式．运用该公式可从化学结构出发计算硝胺单质炸药的燃速和压力指数．通过十种不同类型硝胺单元推进剂燃速的实际计算表明，理论值与实测值十分一致．由此讨论了影响硝胺单质炸药燃速与燃速压力指数的化学结构因素．

| Abstract: | Based on the decomposition mechanism of nitramine, the hypotheses about the thermal decomposition reactions on the initial stage of ten kinds of nitramine monopropellant combustion are put forward. According to the chemical property and the function in the dominant combustion reaction, the gas phase decomposition products near the burning surface of nitramine monopropellants are classified to four kinds, they are oxidizer, reducer/fuel, splitible free radical. The burning rate equation is expressed to be the function of the mole fraction of oxidizer and combustion chamber pressure. From 0.1 to 100 MPa, the burning rate of ten kinds of nitramine are calculated. The results show that the computed value are in good agreement with the experimental value. The effect of chemical structure on burning characteristics are discussed. |
