The authors have obtained the formulas to calculate the parameters of railguns at periodic nonsinusoidal Diffuser current.Such parameters as the average effective magnetic density of current pulse in the space between the railgun tires, the equivalent inductance and resistance, the average temperature of tires at their adiabatic heating as well as the average mechanical tension in tires were determined.At current pulse relative duration at constant average increase of tire temperature the current amplitude, the mechanical tension in tires, the body Cast Iron Cookware peak velocity increase at decrease of current pulse amount and their repetition frequency.In order to produce the railgun tires the chrome bronze may be applied instead of the beryllium one.The chrome bronze is less strong but cheaper and more processable; it possesses higher specific conductivity that increases the efficiency of energy conversion by the railgun.
