An investigation of the gas dynamics of various large naval guns, including the interior ballistics (charge burning, propellant gas expansion and shell acceleration) and the nature of the gas expansion and air shock beyond the muzzle. Solutions are accomplished by a numerical program which integrates the partial differential equations appropriate to the gas dynamics in one space dimension. The equations of state for the gas and air are treated in some detail, as is the nature of the charge burn, the barrel friction, and the shell inertia. The dynamics of the partially burned charge gases which sometimes flash burn after ejection from the muzzle are treated with the limits of expansion into various conical geometries. Comparisons are made with observations of both the interior ballistics and of the smoke, flash, and blast from the exhaust.
