摘要:

本文研究了RDX/AP配比对其HTPB复合推进剂爆温(T_v)、燃烧产物中HCl含量、燃速和燃速压力指数的影响.探索了叔丁基二茂铁、铬酸铅等添加剂对RDX/AP丁羟推进剂燃速的催化效果.应用单幅摄影、中止燃烧和扫描电镜等实验技术对其结果作了初步的分析.

Abstract:

In this paper,the effects of RDX/AP proportion on deflagration temperature (Tv),Hcl content in combustion products,burning rate and burning rate pressure exponent have been studied.The Catalysis effect of tertiary butyl-ferrocene and lead chromate etc.on RDX/AP HTPB propellant burning rate has been examined. Preliminary analysis on test results were made using singlephotograph,suspend burning and scanning electron microscope etc.techniques.
