The Blast Field Produced by a Cannon Having a Perforated Muzzle Brake

Abstract

In a study of perforated muzzle brakes, Nagamatsu, Choi, Duffy, and Carofano calculated the three-dimensional steady flow through one vent hole and used the results to predict overall brake performance. In the present study, the analysis is extended to the calculation of the blast field. The results compare favorably with previously unpublished shadowgraphs obtained by Dillon in his experimental program. Keywords: Muzzle brakes; Perforated muzzle brake; Internal ballistics; Muzzle blast. (EDC)
