Abstract

Propellant deterioration can be kinetically analysed by both Berthelot's law and Arrhenius' law. Kinetic analysis of the mixed stabilizer para‐nitro‐N‐Methylaniline(__p__NMA)/2‐nitrodiphenylamine (2NDPA) based propellant deterioration at different temperatures, during the time necessary for the complete consumption of the more reactive stabilizer __p__NMA, which can be taken as a measure of the safe life of these propellant compositions, gave results for both Berthelot's law and the Arrhenius' law which are satisfactory. However, it was found that the predicted safe life for the propellant compositions according to the Arrhenius law was much longer than that obtained from Berthelot's law. Therefore, from the safety point of view, it is preferable to use Berthelot's law analysis to assess the safe life of double base propellant compositions.
