Abstract

Because the electromagnetic railgun's main current can reach several MA and the muzzle velocity is more than 2 km/s, launching in this harsh environment in barrel will cause grooving to the rail. Using existing experimental data of references, this paper analyses the position and depth analysis of the grooving phenomenon. So this paper design series connected augmented sextupole rails electromagnetic launcher to obtain high inductance gradient. High inductance gradient plays an important role in a novel electromagnetic launcher. Since inductance gradient is the decisive factor to super high speed and reduce high current, this study focuses on the design of launch model and inductance gradient distribution in moving area of double projectile. In this study we will simulate three typical series augmented sextupole rails connection mode, with finite element method and compare them. The theoretical analysis and numerical simulations indicate that the inductance gradient performance of the A configuration is better than other configurations. Therefore, this configuration could reduce the grooving phenomenon of sextupole rails.
