Finite-element circuit model of helical explosive generators
Abstract
A finite element model for helical explosive generators (MCG's) is described. Flux losses due to the moving point of contact between coil and armature are accounted for with a new term in the circuit equation. The term is required since flux which has diffused into the conductors is not lost from the circuit until it is actually switched out by the point of contact. Induced currents in the armature are considered to flow in a circuit which is separate from, but coupled to the load/coil circuit. Conductor ohmic losses are calculated using heat dependent resistivities and a new approximation for proximity effect. Wire branching is accounted for and the model can be used for generators operating in the inductively coupled cascade mode. Calculated and measured performance for explosive generators which differ widely in size and design are compared.
