Abstract: The Influence of HTPB (Hydroxy Terminated Polybuladiene) euring cross-linked system on burning rate of propellant is studied in present paper.lt was dis- covred from experiments that the burning rate of MAPO-bearing solid propellantin curing cross-linked system is ,18.4% higher than that of trialcohol cross-linkedpropellant. Its action mechanism is analysed by means of experimental methodsincluding thermal analysis and interrupting combustion etc.

摘要： 本文研究了HTPB固化交联体系对其推进剂燃速的影响。实验发现,在固化交联体系中含MAPO的推进剂燃速要比用已三醇交联的推进剂燃速高18.4％。应用热分析、中止燃烧、电子扫描显微镜等实验方法,对其作用机理作了分析说明。
