| 摘 要： | 以ＨＴＰＢ推进剂化学老化机理及其氧化反应动力学为依据，导出了推进剂应变保留值与贮存老化时间的关系，由推进剂中氧化剂ＡＰ低温分解反应和ＨＴＰＢ固化体经反应的动力学参数，计算出了在不同应变保留值时的推进剂的贮存寿命。当推进剂的应变保留值在３０％～５０％之间时，其贮存寿命的理论计算值与高温加速老化实验值之间的相对误差小于１６％。

| Abstract: | Based on the chemical aging mechanisms and the oxidation reaction kinetics of HTPB propellants, the relationships between the strain retention value of propellant and the storage life were first infered. According to the kinetic parameters of oxidant lower temperature decomposition reaction and HTPB cure system oxidation reaction of HTPB propellant,the storage life of propellant under different strain retention value was calculated. When strain retention value of propellant was between 30 percent and 50 percent, the relative errors of storage life between theoretical value and high temperature accelerated aging experimental results were below 16 percent. |
