Abstract

A system engineering code that simulates the performance of a railgun/power supply system is described. The code, named EGCAC (electromagnetic gun circuit analysis code), accounts for many performance degrading effects, including viscous drag on the armature, viscous drag on the gas being pushed in front of the projectile, entrained gas that must be accelerated in front of the projectile, time-dependent rail resistance, armature resistance, system resistance, and ablation drag. EGCAC has been utilized to predict railgun performance up to a velocity of approximately 4 km/s for experiments at several laboratories. The theory of EGCAC is described, and sample calculations are presented
