【Abstract】 Activation energy methods for rapidly predicting service life of propellants were investigated.The results show that the caculated data using the point slope method and routine accelerated ageing method are almost indentical,and the data using the two point method(70℃,50℃)are most approximate to those using routine method.The dynamic method for determination of activation energy is a promising approach in the rapid prediction of service life of compostite solid propellants.更多还原
