Abstract: A new electromagnetic launcher was designed based on the basic structure of helical coil electromagnetic launchers （HCEL）. The moving processes of helical coil electromagnetic launchers （HCEL） with coil armatures and ferromagnetic armatures were analyzed numerically. Analyzed the force and velocity versus time of the two armatures contrastively.
Key words: electromagnetic launchers; HCEL; numerical emulation
