By studying and summing up the common failure physical models and combining
with the quantum mechanics theory on the relationship between the electronic equipment aging reaction
rate and tempreture-humidity，a hygrothermal aging life model for solid propellant storage and
usage is established with the propellant mechanical properties a8 the re．arch object．Further more，
experiential formula was obtained by fitting experimental datum．The model call be used as a theory
basefor the prediction ofihe storage life time span of solid rocket propellant under hygrothennal en·
vironment．or鹪a reference model for the calculation of the residual life of SRM．
