Abstract

Abstract: In the present study, the safe storage 1ife prediction of gun-propellant in different temperature mode were calculated by the dates of stabilizer content under thermal accelerated aging at temperature of 95°C, 90°C, 85°C, 75°C and 65 °C via Berthelot equation and Arrhenius equation. In order to demonstrate these predictions, all the estimation results have been compared with the real experimental results. Presented results indicate that the prediction via Arrhenius equation is consistent well with real storage experimental results at shallower reaction depth of stabilizer (α = 6.6%). Furthermore, predicting by shallower Berthelot equation is available at deeper reaction depth (α = 50%).
