THE EXPERIMENTAL STUDY OF THE THERMAL AGEING COMBUSTION PROPERTY OF THE MODIFIED DOUBLE BASE PROPELLANT AND ITS LIFETIME CALCULATION

摘要

By using the closed combustion apparatus, the present paper deals with the experimental study for the combustion property of the modified double base propellant after its thermal aging. And the storage life is calculated by using the curve of combustion speed over ageing. This result is then compared with the storage life calculated by using the ceritralite method. The consistency of the two results shows that the experiment of the propellant combustion speed over ageing veritably demonstrates the ageing property of the modified double base propellant.
