Research on Structure Design of Multipole Field Reconnection Electromagnetic Launch Mode Drive Coil

Multipole field reconnection electromagnetic launchers are highly excellent electromagnetic launchers, which have many adjustable parameters. This article proposes a new topology of the trapezoidal coil structure. Through simulation analysis, it is found that this new coil structure power supply can make the original launch mode have better launch performance. The trapezoidal drive coil configuration can accelerate a 0.49-kg projectile armature to 676.5 m/s, while the rectangular drive coil configuration can accelerate the 0.49-kg projectile armature to 658.3 m/s, which can provide a design idea for the drive coil.
