Roggla's Equation and Its Application to Interior Ballistic Problems (Revised)

Abstract

Some time ago Roggla published a series of interior ballistic charts together with a pamplet explaining the method of computing velocities and pressures. While these charts have a useful field of application, the theoretical treatment of Roggla may also be used advantageously in calculating, without their aid, the performance of a new weapon when interior ballistic data for a weapon differing not too widely from it in caliber, muzzle velocity etc. are known or in calculating the effect of a change in bullet weight, web thickness etc. in a given weapon. For this reason, an exposition is given of the deduction of Roggla's equation and a description of the method of its application to interior ballistic problems.
