The Effective Velocity of Escape of the Powder Gas from A Gun

Abstract

The effective velocity of escape of the powder gas from a gun, as defined by Eq. (1), is a quantity that is independent of the mass of the recoiling parts. It is the purpose of this report to develop a method for predicting the escape velocity that will be satisfactory for values of the ratio of the mass of the charge to that of the projectile as large as unity. The theory follows Hugoniot in treating the efflux of gas after departure of the projectile as equivalent to the emptying of a reservoir through a nozzle values of quantities at the breech being used for value in the reservoir.
