Computer Implementation of a Muzzle Blast Prediction Technique

Abstract

A computer code is developed which generates contour maps of peak incident overpressure, peak reflected overpressure, blast wave time of arrival, and blast wave positive phase duration. The code is based upon a free field muzzle blast scaling techniques which is extended to treat blast wave reflection from surfaces. The predictions of the code are shown to compare reasonably well with experiment.
