| 目的 研究超期服役的某型导弹发射装药是否满足安全贮存使用要求，结合性能试验准确评估装药的贮存安全性。方法 通过分析发射装药性能老化与失效可能引发的安全风险，构建装药贮存安全性评估参数体系。在此基础上，对贮存14 a与5 a的发射装药分别进行结构完整性、力学性能、热安定性、易损性等贮存安全性相关试验。结果 通过试验结果与数据分析，获取了对应的评估参数，贮存14 a与5 a的装药性能相比，装药总体结构安全系数由3.85降至2.86。在相同试验温度下，抗拉强度、抗压强度和抗冲击强度的最大降低幅度分别为18.35%、14.05%、7.85%，装药安定剂含量由98%降至93%，摩擦感度与撞击感度分别增高33.28%、36.77%，据此综合评估了发射装药的贮存安全性。结论 超期服役的某型导弹发射装药贮存安全性仍满足技术标准要求，装药经过长期贮存后，力学性能和热安定性的劣化程度较小，结构完整性与易损性对应参数变化较大，表明装药的使用安全性明显下降。 |

| The work aims to test and evaluate the propellant charge’s storage safety in combination with performance tests to study whether the propellant charge of a certain type of missile in extended service can meet the safe storage and use requirements. The safety risks caused by the propellant charge’s performance aging and failure were analyzed, accordingly the evaluation parameter system of the propellant charge’s storage safety was built. On this basis, the storage safety tests of the propellant charges for 14 years and 5 years were implemented in terms of structural integrity, mechanical properties, thermal stability and vulnerability. By the comparative analysis of test results and data, the corresponding evaluation parameters were obtained. The performance changes of propellant charges stored for 14 years were compared with those stored for 5 years. It showed that the overall structural safety factor decreased from 3.85 to 2.86. At the same testing temperature, the maximum reduction of tensile strength, compressive strength and impact strength was 18.35%, 14.05% and 7.85% respectively. The stabilizer content decreased from 98% to 93%, and the friction sensitivity and impact sensitivity increased by 33.28% and 36.77%. Resultingly, the storage safety of the propellant charge was evaluated comprehensively. The comprehensive evaluation results suggest that the storage safety propellant charges in extended service still meet the requirements of technical standard. After long-term storage, the thermal stability and mechanical properties' changes of the propellant charges are minor, but the corresponding safety parameters' changes of the structural integrity and vulnerability are large. Those indicate that the propellant charges’ use safety decreases significantly. |
