An Evaluation of Muzzle Flash Prediction Models

Abstract

Secondary muzzle flash results from the reignition of a mixture of fuel-rich exhaust gases and entrained air. This combustion process releases energy in the form of light, the objectionable 'flash', and also noise, in the form of secondary blast which adds to the primary blast of the weapon. Three different techniques for predicting secondary flash occurrence have been tested in simulated artillery and mortar firing situations. The predictions of the techniques are compared, and, where observational data exist, the predictions are compared to them. The Standard Plume Flow (SPF) code, for rockets, has recently become available. While we found that it is not yet ready for application to guns, it has many appealing features.
