AP复合固体推进剂燃烧模型

本文提出了一个复合固体推进剂的综合燃烧模型和相应的数学处理方法。该模型对凝聚相反应作了更细微的分析,特别重视和强调了各种热量传递对燃烧所起的作用,并以推进剂中处于连续相的粘合剂线性分解速度表示推进剂的线性燃速。根据此模型编制程序并进行了大量计算。计算结果与实验符合得很好。对AP/HTPB多级配推进剂的计算结果中,相对误差小于10％的占80％,对Ae/AP/HTPB推进剂则占90％以上。

A MODEL OF COMPOSITE SOLID PROPELIANT COMBUSTION

A comprehensive model describing the combustion of composite solid propellants has been developed in this paper. This model discusses in more detail the condensed-phase reactions, emphasizes the importance of the heat transfer in all forms on the burning surface and proposes that the linear combustion rate of propellant should be expressed by the Linear decomposition rate of the inert binder. A Large number of concrete calculations have also been made and compared to the experimental data. For the AP/HTPB propellants, the calculated results of which the relative error is Less than 10% make up 80% and for the AL/AP/HTPB, make up more than 90%.
