Abstract:

It has been conclusively demonstrated that aqueous foam can effect significant greater than 10 dB reductions in major-caliber 554 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.
