Propellants, Explosives, Pyrotechnics, Volume 50, Issue 7, Page 106-114, July 2025.ABSTRACT The decomposition mechanisms of double base rocket propellants are well known and reported, but the influence of atmospheric conditions such as water and oxygen is poorly understood. In this work, the influence of water and oxygen on an extruded double base (EDB) rocket propellant aged between 70 and 100°C was examined using heat flow ...
