Effect of variations in loading conditions on the internal ballistics of guns

Abstract

In this paper tables have been constructed to show the variations in the position of all-burnt and pressure at all-burnt with variations in the Central Ballistic Parameter M and the shot-star pressure Z0. It has been shown how the whole table for the variation of maximum pressure with variations in M and Zo(for tubular propellants) can be represented by a single graph. Also assuming zero short-start pressure the internal ballistic equations have been expressed in a slightly different form and expressions have been obtained to relate pressure and velocity with short- travel. Further the variations in maximum pressure and muzzle parameters have been calculated.
