| Abstract: | 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. |
