ESTABLISHING FUNCTIONAL RELATIONSHIP OF INTERNAL BALLISTIC AND UTILIZATION COEFFICIENT OF THE GUN BARREL BORE VOLUME

Open full text 0 citations

Abstract

This paper establishes an internal ballistic correlation for conventional guns as a function of travel of the projectile in the barrel bore. This function has three parameters that match calculation results or experimental results. Three parameters are determined by these characteristics: maximum pressure of propellant gases, muzzle pressure of propellant gases, and muzzle velocity of the projectile. According to the ballistic correlation, the utilization coefficient of the barrel bore volume for a specific gun can be evaluated by maximum pressure and muzzle pressure.
