Simulation of Helical Flux Compression Generator

Diverse approaches to helical flux compression generator's (HFCG) inductance, resistance, and armature expansion calculations are evaluated. Comparison of simulated and experimentally obtained results is provided. Validity criteria for different simulation models are proposed. Consideration of armature acceleration under the pressure of detonation products and magnetic pressure is shown to be beneficial for accuracy of HFCG simulation. Control of HFCG temperature during simulation enables detecting the critical points of system operation.
