FIELD: electricity.
SUBSTANCE: rail electromagnetic accelerator includes power housing which contains rails and magnetic bias coils connected in series through armature with current source, which slides along rails. Magnetic bias coils are used not only to decrease current loads on armature, but also to decrease power loads on rails (magnetic "suspension"); for that purpose, rails are two-layer and made of current-carrying and current-transmitting parts and vibration insulated from housing, coils and armature.
EFFECT: improving stability of output characteristics and life time.
