HTPB复合固体推进剂老化研究进展

综述了HTPB推进剂在老化试验和表征方法、老化机理、模型构建和寿命预测方面的国内外研究现状，通过对国内外的HTPB推进剂研究历程进行对比，分析了与国外研究整体趋势的差异。从检索文献来看，与国外研究进展相比，国内研究整体上具有起步晚、发展快的特点。在此基础上，展望了今后的研究方向，包括多因素耦合的老化机理探究、老化快速评价、先进监测手段、寿命预测模型优化以及防老化等方面，以期为HTPB推进剂的老化研究提供更多参考。

Research Progress on Aging of HTPB Composite Solid Propellants

The work reviewed the domestic and international research on HTPB propellant in terms of aging experiments and characterization methodologies, aging mechanism, model construction and life prediction. By comparing the domestic and international research history of HTPB propellant, the overall research gap between China and foreign countries was clarified. According to the literature retrieval, compared with international research history, domestic research had the characteristics of late start and rapid development. On this basis, the domestic research prospects were proposed accordingly, including the deep investigation of the mechanism of multi-factor coupling aging, fast evaluation methods, advanced monitoring methods, optimized evaluation models, and anti-aging, so as to provide more reference for the aging research of HTPB propellant.
