This paper simply describes the working principles and the process of the initial driving device of the self energizing gatling gun. A mathematical model for the initial blank cartridge driving process of the gatling gun is presented based on the gas dynamics and the mechanical dynamics.The numerical simulation investigates the effects of the parameters of the initial driving device and the parameters of the blank cartridge on the piston chamber pressure and piston velocity as well as receiver rotation speed.Calculation shows that the movement regulations of the piston velocity and displacement, the receiver rotation speed and rotation angle are well simulated.
