Abstract: The study on aging properties of solid propellant and the prediction of its safe storage life is of great importance for the safe storage of ammunition. Research progress of aging properties of solid propellant is reviewed，including aging mechanism，influencing factors，testing methods and prediction of storage life. The cross linking of adhesives by oxidation is the main reason for aging failure. The composition，structure and mechanical properties of the propellant are the intrinsic factors and ambient temperature and humidity are external factors . Combination of analytical instruments and experiments is an effective method to shorten the experimental period and improve result accuracy. The multi-scale simulation study based on computer will be the focal point in the future.

Key words: solid propellant, aging mechanism, influencing factors, computer simulation

摘要： 研究固体推进剂的老化性能，预测其安全储存寿命，对弹药安全储存具有重要意义。本文从固体推进剂的老化性能机理、影响因素、测试方法以及储存寿命预测等方面综述了近年来国内固体推进剂老化性能的研究进展，认为固体推进剂的老化失效主要是由黏合剂氧化交联所致，推进剂自身的组成、结构和力学性能是决定其老化性能的内因，而外部因素主要有环境温度、湿度等。研究手段多采用分析仪器与实验相结合的方法，以缩短实验周期，提高结果准确性。以计算机为载体的多尺度模拟研究将是今后固体推进剂性能研究的重点。
