Reduction of 5in./54 Gun Blast Overpressure by Means of an Aqueous Foam- Filled Muzzle Device

Abstract

It has been conclusively demonstrated that aqueous foam can effect significant (greater than 10 dB) reductions in major-caliber (5'/54) gun muzzle blast peak sound pressure level; reduction of more than 15 dB was attained. Containment of the foam in a muzzle-mounted canister was investigated. This report addresses related areas of gun ballistics, interior barrel ballistics, effects on projectile velocity, and general gun operational effects.
