Muzzle-Center based Scaling Law for the Peak Overpressure of a Cannon Blast

ROBERT A. CARSON, ONKAR SAHNI

Abstract


For large caliber cannons, blast overpressure can have a detrimental effect on the crew in the near field (i.e., within a distance of 50 tube diameters or calibers from the muzzle center) as well as on the support personnel and equipment in the far field (i.e., at a distance greater than 50 calibers). Therefore, an efficient method to determine the peak overpressure due to a cannon blast is highly desired. In this study, we investigate a muzzle-center based scaling law for the peak overpressure due to the primary blast of a large caliber cannon.
