Abstract: In this paper a new experimental method for propellant age is discussed, which includes to accel’elerate the age of propellants made in different years at a high temperature, to test the motors periodically, to take internal ballistic parameters of motors and the required physical and chemical performances of propellants as criterion of propellant inefficiency. The service life of propellants can be calculated according to the relationship between the propellants made in different years and the invalid time. A simple method to calculate acceleration factors and the service life of propellants is presented in this paper. The concerned experimental results are also introduced generally.
