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.

Design and experimental study of a detonator using a lengthy exploding wire fuse are proposed. A shock-wave unit using electrically exploding wire for initiating high-explosive charges to create axially symmetric detonation front is developed. The detonators are made and tested in two designs. The design details and the results of experiments are reported.
