摘要:
端羟基聚丁二烯(HTPB)推进剂作为固体发动机的燃料具有极佳的力学和弹道性能,是世界各国使用的主要推进剂。开展HTPB推进剂高温加速老化性能研究,对掌握HTPB推进剂贮存条件、分析推进剂老化机理、预估贮存周期具有相当重要的意义。分析了不同老化温度对复合固体推进剂燃烧性能的影响,即对推进剂燃烧热值造成的影响。通过测试不同热老化的HTPB推进剂的燃烧热值,得到老化后HTPB推进剂热值的变化规律,并拟合出HTPB推进剂燃烧热值与老化温度、时间的函数关系。
Abstract:
HTPB propellant as the fuel of solid motor, has excellent mechanical and ballistic properties which is the main propellant used in countries around the world for a long time. The study of HTPB propellant accelerated aging performance at high temperature is of great significance to master the storage conditions of HTPB propellant, analyze the aging mechanism and predict the storage period. The effects of each component on the combustion performance for the composite solid propellant during the aging process are analyzed, namely the effects on the combustion calorific value of the propellant. By testing the calorific value of HTPB propellant with different aging degrees, the variation law of calorific value for HTPB propellant after aging is obtained, and the relationship between the calorific value of HTPB propellant and aging temperature and time is fitted.
