Abstract

In order to evaluate aging kinetics and disclose aging mechanism of composite solid propellant under cycling temperature loading, the limit that the method to process data in traditional high temperature accelerated aging for cycle temperature accelerated aging was discussed. The aging kinetics model under cycle temperature was built. The method for calculating equivalent temperature and equivalent cycling time and formula for calculating activation energy was given. The aging mechanism of composite solid propellant under cycling temperature condition was proposed. Those methods make life prediction accord with actual storage condiction with better correlation.

Key words： composite solid propellant; cycling temperature; aging kinetics; equivalent temperature
