The Hygrothermal Aging Life Models of Solid Propellant

Abstract:

The temperature and humidity are two main environmental factors, which have influence on the life of solid propellant. Comparing with single factor aging life model, hygrothermal aging life model is more feasible, which takes temperature and humidity into consideration. In this paper two hygrothermal aging life models were established. The data of hygrothermal aging test of solid propellant was used for multiregression. According to significance analysis and comparison of two models, it was shown that two models both fit the test data well. Storage life of the solid propellant under normal condition was obtained by using the life models. The results of the research can provide reference for storage life prediction of solid propellant.
