Model of helical magnetic compression generators with explosive initiated axially

The model of helical generators whose explosive is initiated axially (MFCG) with a high inductance load has been set up in this paper. Based on the model of the MFCG that consists of 1D model for explosion driven central tube (armature), a model for magnetic field distribution inside the helix, a model for magnetic force outside the center tube and the circuit model, a code (CEMG 1.0) was compiled. Calculation results show that, the output current and pulse duration of MFCG can be enlarged as the distance between the central tube and the stator helix increases. The generator with smaller pitch of feed coil can output higher current on the load, and the generators with an aluminum tube can output shorter pulse duration than those with a copper tube.
