The Reduction of Muzzle Pressure Without the Reduction of Muzzle Velocity in a Davis Gun
Abstract
This study devises a means of reducing the maximum pressure at the counterweight muzzle of a Davis Gun without reducing the muzzle velocity of the primary projectile. A new counterweight is designed, with constant area ducts placed longitudinally through the counterweight. A proper combination of duct length, duct cross-sectional area, frictional resistance, and the number of ducts, allows the right mass of propelling gas to flow through the counterweight, so that the pressure of the gas fore and aft of the counterweight never reaches the maximum allowable pressure at the muzzle, even when additional propellant is placed in the chamber to keep the primary projectile velocity constant.
