Electromagnetic Launcher : Review of Various Structures

Abstract

A theoretic review of electromagnetic coil-gun launcher and its types are illustrated in this paper. In recent years conventional launchers like steam launchers, chemical launchers are replaced by electromagnetic launchers with auxiliary benefits. The electromagnetic launchers like railgun and coil-gun elevated with multi pole field structure delivers great muzzle velocity and huge repulse force in limited time. Various types of coil-gun electromagnetic launchers are compared in this paper for its structures and characteristics. The paper focuses on the basic formulae for calculating the values of inductance and resistance of electromagnetic
