Combustion of RS-41

Abstract

The pyrotechnic composition RS-41, a mixture of 49 wt.% KClO4, 49 wt.% Al/Mg and 2 wt.% Calcium Resinate, is an important ingredient in the MP (Multipurpose) ammunition. RS-41 placed in the front of the projectile ignites due to impulse transfer by impact. A pyrotechnically combustion starts and spreads backward in the projectile and towards the explosive. This gives a delay that is important for the fragmentation effect of the warhead. This report do analyses Closed Vessel experiments performed on RS-41.
