During operation of electromagnetic launcher (EML), the electric energies from power supply are mainly converted to the magnetic energy in the launcher, joule heat loss and the kinetic energy of armature. The magnetic energy in helical coil electromagnetic launcher (HEML) are not only consumed by the muzzle arc but also lost in commutation process. The magnetic energy loss in commutation process,...
Helical coil electromagnetic launchers (HEMLs) using rail-fed strategy, local excitation and single-turn commutation, solve the problem of synchronization control perfectly. Through the simulation, a novel helical coil launcher is designed using the basic HEML's structure. A D-shaped cross section armature is proposed to achieve the maximum projectile velocity. The energizing length of the driving...
