The Optimized Design of Multistage Induction Coilgun with a Novel Asymmetric Structure

Document Type : Original Article

Abstract

Nowdays, multistage  induction  coilguns,  despite  their  special  complexity,  have  increasingly  attracted  attention
due  to  their  ability  to  accelerate  large-to-massive  projectiles.  Coils  in  a  multistage  induction  coilgun  are
energized sequentially to provide currents that create forces to accelerate the projectile. In symmetric structure,
the  length  of  coils  is  equal  but  in  the  asymmetric  structure,  the  length  of  coils  is  different  and  decreases
gradually.    An  asymmetric  multistage  coilgun  with  asymmetric  structure    is  proposed  in  this  paper.  Different
lengths, number of turns, and switching times are chosen for each individual coil to get better results. The time
stepping finite-element  method  is utilized  to  obtain  the simulation  results.  Three asymmetric  models  have  been
compared with three symmetric models. The results show that the asymmetric structure has a better performance
and has 6.57% higher output maximum speed than the symmetric structure on the average. In addition, the best
model for obtaining the maximum projectile speed has been derived. Furthermore, this model has 11.52% higher
output speed and 62% lower length than the other models.
