The muzzle blast from a 30 mm cannon is examined both experimentally and theoretically. Data are collected describing the blast overpressure in the free field and upon a surface adjacent to the cannon. Scaling relationships are demonstrated to describe both pressure pulses reasonably well. The influence of muzzle devices upon the blast and flash characteristics of the weapon is examined.
