Abstract: The relationship between the oxidation reaction heat effect of HTPB propellants gel and mechanical properties of HTPB propellants during storgae aging was studied.The results indicate that during storage aging the oxidation reaction heat effect has a good linear relationship to the strain under ultimate tensile strength of propellant.This provides a small quantity,quick simple and convenient new method for the storage life of HTPB propellant estimation.

Key words: Hydroxyle terminated polybutadiene propellant;Agingtest;Storage life;Gel

摘要： 研究了贮存老化过程中 HTPB推进剂凝胶的氧化反应热效应与推进剂力学性能之间的相关性。实验表明 ,HTPB推进剂贮存老化过程中 ,凝胶的氧化反应热效应与推进剂最大强度下的延伸率 ,二者之间存在很好的线性相关性 ,为进一步快速预估 HTPB推进剂的贮存寿命 ,提供了一种样品用量少、快速简便的新方法
