Abstract : An electromagnetic (EM)projectile design is evaluated by adopting finite element procedures similar to those employed in the analysis of kinetic energy (KE) projectiles from conventional cannons. The specific assumptions required to tailor the analysis to the unique aspects of the EM system are detailed. Quasi-static analysis runs are made for two different acceleration levels and are used to compare against the results of five transient analyses having various loading profiles. Lastly, recommendations are left for the EM projectile designer of specific areas of concern which must be examined in future projectile analysis.
