摘　　要：应用加速老化试验方法对空间推进系统产品贮存性能进行评估,首先基于空间推进系统产品的结构组成,开展各部组件的贮存性能分析,确定非金属材料部组件为该系统的薄弱环节;然后依据非金属材料的加速老化试验结果,确定空间推进系统组件级、系统级加速贮存试验条件;最终综合相关试验结果,得出全系统产品贮存寿命的评估结论。The accelerated aging test method is applied for the evaluation of the storage performance of the space propulsion system products.Based on the structure composition of the products of the space booster sub-system,the storage performance of various components is analyzed and the non-metallic materials are identified as the weak link of the sub-system.Based on the accelerated storage experiment results of the non-metallic components,the acceleration factors for the various parts are calculated and are applied to the components and the whole space booster sub-system.According to the related experiment results,the evaluation conclusion of the whole system storage life is reached.
