Computer Simulations of the Electrothermal Behavior of Armatures During Electromagnetic Launch. Part 3: Miscellaneous 2-D Simulation Results.
Abstract
Recent results of simulations of the electromagnetic acceleration process with the 2-dimensional electrothermal finite element computer code ET-code are presented and three extensions of the code, the muzzle voltage calculation, the melt-wave model and the frictional heating model, are described. In order to obtain a uniform current distribution in the solid armature during launch, necessary for postponing the transition of the armature to a hybrid one, three possible methods were investigated, i.e. the application of a resistive layer on the rails, the use of fibre armatures with tipped fibres and the lengthening of the armature.
