Interior Ballistics of Recoilless Guns

Abstract

A system of interior ballistics is developed for guns in which the recoil is eliminated by the rocket action of powder gas flowing through a Venturi in the breech. The system is illustrated and applied to numerous examples including the German 7.5-cm Leichtes Geschutz. This system makes possible prediction of the performance of such weapons with an accuracy comparable to any of the leading ballistic systems. The equations for the interval of burning of the powder are reduced with the help of simple approximations to the equations valid for the corresponding interval in conventional guns. Since the adiabatic law holds in this case as well as in conventional guns and rockets, an approximate solution for the interval after the powder has burned is easily obtained.
