摘　　要：为得到含硝酸酯螺压推进剂装药在自然贮存过程中性能变化规律,对贮存于某库房(贮存温度–10~35℃,相对湿度≤85%)12年的装药进行了系统性能测试与研究。结果表明,推进剂药柱的药形尺寸、理化性能、化学安定性、内部质量、力学性能、燃速及感度等性能未发生明显变化,装药的内弹道性能略有降低,但满足技术要求,表明该装药使用寿命至少能达12年。In order to obtain the performance change rules of the screw extrusion propellant charge containing nitrate ester during the natural storage,The system performance of the charge stored in a warehouse(the storage temperature is–10~35℃,the relative humidity is not more than 85%)for 12 years was tested and investigated.The results show that the performance of the propellant charge including the grain size,physico-chemical performance,chemical stability,internal quality,mechanical performance,burning rate,sensitivity and so on has not significant change,and the interior ballistic performance of the charge reduces slightly,but the technical requirements can be met,it shows that the service life of the charge can reach at least 12 years.
