An Evaluation of Temperature and Heat Flux of Gasless and Gassy Percussion Primers

Abstract

A knowledge of the energy output of precussion primers is paramount in assessing their suitability as igniters in pyrotechnic devices A simple heat flux probe is described that is described that is used to compare the therma output of gasless and gassy percussion primers. Temperature and heat flux were measured for both primers at a range of distances from the primer vent. Analysis shows the gasless primer produces a greater heat flux and larger temperature than the gassy primer indicating a larger temperature than the gassy primer indicating a larger thermal energy output. Keywords: Primers(Explosives); Igniters; Temperature measurement; Heat transfer.
