Multipole Field Electromagnetic Launchers (MFEML) is one of the radial electromagnetic launching mechanisms, which can propel a payload for long distances. This paper proposes formulae for inductance based on the magnetic flux distribution in the coils of MFEML. Flux lines flow is sectionalized, for each section reluctance formulae is derived based on the position of the projectile. Based on the principles of the Lorentz equation, magnetic forces are calculated. This paper presents an electrical and magnetic equivalent circuit of MFEML. The velocity and force characteristics are obtained for the proposed formulae. The results are validated using Finite element analysis.

Initiatives in electromagnetic propulsion all over the world are aimed at the development of electromagnetic launchers. This paper presents the constraint based design of Multipole Field Electromagnetic Launcher (MFEL). A design algorithm is developed based on Gauss iterative method. Muzzle velocity is considered as the objective function and the length, diameter and thickness of the accelerating coil are considered as constraints. The results for hexapole, octapole, decapole, dodecapole and hexadecapole cases are compared and tabulated.
