Design and Characterization of High Efficiency Single-stage Electromagnetic Coil Guns
The study improved coilgun efficiency by testing several novel methods: using a permanent neodymium magnet instead of ferrite, employing stepped multilayer coils with non-uniform windings, and implementing precise current pulse timing. These enhancements resulted in a significant efficiency increase to 1.78%, demonstrating that strategic modifications lead to higher projectile velocities and better energy conversion.
