| 目的 建立一种HTPB推进剂自然环境加速老化试验方法。方法 研发一套户外热循环自然环境加速试验装置，可以模拟和强化太阳辐射对HTPB推进剂的热效应和昼夜温差冲击效应，并保持环境温度日夜温差循环、季节温差循环的特点。利用该装置，在海南万宁试验站户外暴露场开展HTPB推进剂自然环境加速老化试验及其验证试验，设定试验最高温度不超过70 ℃，并同期开展HTPB推进剂库房贮存试验。从模拟性、加速性、重现性评价自然环境加速老化试验方法的可信度。结果 随着老化时间的延长，最大拉伸强度保留率波动下降，可作为HTPB推进剂敏感力学参数。与该推进剂在库房贮存不同时间的最大拉伸强度保留率相比，在置信度为99％，两种试验方法的Spearman秩相关系数为0.93时，自然环境加速老化试验方法对于库房贮存试验方法的加速倍率为5倍，自然环境加速老化试验重现性良好。结论 建立了一种适用于HTPB推进剂的简单易行、模拟性强、加速倍率高的自然环境加速老化试验方法，能再现HTPB推进剂在实际库房贮存的力学性能变化规律。 |

| Objective To establish a natural environment accelerated aging test method for HTPB propellant. Methods A set of outdoor thermal cycle natural environment accelerated aging test device was developed, which could simulate and enhance the thermal effect and the impact effect of temperature difference between day and night of solar radiation on HTPB propellant, and maintain the characteristics of daily and seasonal temperature cycle. The HTPB propellant natural environment accelerated aging test and its verification test were carried out with this device in the outdoor exposure field of Wanning Experimental Station in Hainan. The maximum temperature of the test was set to not exceed 70 ℃. HTPB propellant warehouse storage test was carried out at the same time. The simulation, acceleration, reproducibility of the natural environmental accelerated aging test method was evaluated to obtain its credibility. Results As the aging time was extended, the maximum tensile strength retention rate decreased, which could be used as a sensitive mechanical parameter of HTPB propellant. Compared with the maximum tensile strength retention rate of the propellant stored in the warehouse at different times, the confidence level was 99%. The Spearman rank correlation coefficient of the two test methods was 0.93. The acceleration rate of natural environment accelerated aging test method for warehouse storage test method was 5 times. And the natural environment accelerated aging test had good reproducibility. Conclusion A simple, high-simulation and high-acceleration natural environment accelerated aging test method suitable for HTPB propellant is established. It could reproduce the change of mechanical properties of HTPB propellant in actual warehouse. |
