HTPB推进剂贮存老化建模及寿命预估研究综述

HTPB复合固体推进剂是火箭发动机的动力之源，其贮存寿命和性能优劣决定了火箭发动机的寿命和作战性能的发挥，因而研究HTPB复合固体推进剂的贮存老化模型及寿命预估具有重要的军事和经济意义。本文对复合固体推进剂贮存老化性能的研究方法进行了介绍，并综述了国内外贮存寿命老化建模的研究进展，针对推进剂实际贮存可能出现的问题对未来贮存寿命预估的发展趋势进行了预测。研究结果表明，现代仪器的运用可以弥补传统仪器在固体推进剂老化性能研究上的不足，但是还存在研究手段单一、测试方法存在误差、没有形成统一的系统等缺点；推进剂的老化过程比较复杂，结构完整性分析和老化试验相结合的方法可以对推进剂贮存性能和寿命预估进行系统性的研究，得到的结果更准确，可靠性更高。分段老化建模作为推进剂寿命预估研究的新方向，具有很大的发展空间。

Review of the research of aging modeling and life prediction for HTPB propellant

HTPB composite solid propellant is the power source of the rocket engine,which storage life and performance determine the life and combat performance of the rocket engine,therefore the research of HTPB composite solid propellant storage aging model and life prediction has important military and economic significance.In this paper,the research progress of the domestic and international research methods for composite solid propellant storage aging performance is introduced and the research progress on modeling of storage life at home and abroad is reviewed.In view of the potential problems in the actual storage of propellant,the development trend of future storage life prediction is predicted.Research results show that,the application of modern instrument can make up the deficiency of the traditional instrument in the research on the aging property of solid propellant,but there are still some shortcomings such as single means of research,error of testing method and without unified system. The propellant aging process is relatively complex,and the combination of structural integrity analysis and aging test can make a systematic study on the storage performance and life prediction of propellant,and the results obtained are more accurate and reliable.Segmented aging modeling is a new direction for the research of the prediction of propellant storage life,which has great development space.
