摘要: 分析了RDX在平台催化中的作用,认为RDX对平台催化有正、负两方面的影响。据此提出了RDX-CMDB推进剂平台催化燃速模型。导出的燃速公式能够定量地描述平台燃烧现象的各个阶段。在MTW-1推进剂基础配方的应用表明,计算值与实测值之间的平均相对误差小于10%。

Abstract: In this paper the effect Of RDX on plateau combustion is analysed and considered both positive and negative. A model for RDX-CMDB propellants with Pb-Cu-C catalysts is also established. The burning rate formula may be used to discribe all stages of plateau combustion quantitatively.
