Based on the quantum mechanics theory on the relationship between the electronic equipment aging reaction rate and temperature-humidity, the solid propellant hydrothermal aging life span model was established by combined with the Eyring and Arrhenius aging model. Further more, experiential formula was obtained by fitting experimental datum. The HTPB solid propellant storage span under normal temperature 20°C and humidity 50% was predicted by this formula, which was compared with actual storage span. The results show that the predicted service life of the propellant can be more similar to the actual service life by means of dynamics formula with temperature-humidity involved.
