Spice-Based Code for ARL's 4.5-MJ Electromagnetic Launcher Pulsed Power Supply System

摘要

A Spice-based code (Ispice/4Rx) is used to simulate the U.S. Army Research Laboratory's (ARL's) 4.5-MJ pulsed power supply (PP S) discharge into an EM (electromagnetic) railgun. The code determines the in-bore projectile position, voltage, and current at the breech, and exit current and velocity at the muzzle exit The code also includes a diffusion model of the railgun rails. The code's primary inputs are the charging voltage to the PPS capacitor banks and the parameters for the different inductive and resistive components of the system which model its hardware. The railgun parameters were chosen to reflect current hardware and program requirements.
