Design a Novel Plasma Launcher in Railgun
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
An Electro Magnetic (EM) launcher can be utilized as an observational tool to accelerate low-mass specimens up to 350 m/s to study impact phenomena. A plasma armature is used to avoid the friction developed by a sliding metal armature. High current flows are applied to achieve high accelerations, resulting in high plasma temperatures. Yet to our knowledge, there are no existing design methods to control the plasma temperature so we propose a new model using gold coil and plasma gases to reduce the plasma temperature and armature friction. For this purpose, 2-D and axisymmetric plasma models are widely used as these are less complicated and fairly available. This proposed model solves the drawbacks of rail guns, these simulations are performed using Comsol Multiphysics version 4.3b software.
