A Driven Model Research of a Parallel Coil Gun

Abstract

Compared with the coaxial coil gun, the structure of parallel coil gun is conducive to release the effective load which carried by the emitter, and easy to add the suspension device. So, for some massive emitter which could not be easy wrapped inside of the barrel, to design an open parallel coil gun with a high temperature superconducting (HTS) maglev assist device is great significance. The directions of driving force are inconsistent during the drive current pulse up and down under only one coil driven. Eliminating the resistance is an effective way to improve the emission efficiency. A new mode of single-stage and multi-stage driven is designed in this paper. The pulse link up method between the various coils is analyzed. And then a small parallel coil gun model is established in the finite element software ANSOFT. The propulsion effects of single-stage and two-stage driven are simulated. And the feasibility of this driven mode is verified by these simulation results.
