INFLUENCE OF THE GRADUAL IGNITION OF A POWDER IN A GUN AND OF ITS NONSTATIONARY AND EROSION BURNING ON THE INTERNAL BALLISTICS OF A GUNSHOT

A mathematical simulation of the internal ballistics of a shot from a gun, depending on the design of the charge of the gun, has been performed. A general system of equations defi ning the unsteady movement of a two-phase gas– powder mixture in the channel of the barrel of a gun in the one-dimensional approximation is presented. Results of simulation of a shot from a gun charged with tubular powder or chopped powder are presented. The infl uence of the gradual ignition of a powder in a gun and of its nonstationary and erosion burning in it on the parameters of the ballistic process in the gun and the infl uence of the mass and disposition of an igniter in the gun on the dynamics of a shot from it were investigated
