The numerical in nonhomogeneous simulation for qualitative particularities of distributions of the three-dimensional fields subregions of lectromagnetic launcher

The qualitative particularities of distributions of the nonstationary three-dimensional physical fields in the channel of electromagnetic launcher of railgun type have been explored by means of numerical experiment method. It was considered the variant of launcher, having cylindrical geometry. The particularities of fields for three variants of geometry of accelerated armature, including the case of non-one-connected conducting part, have been studied. The picture of power and heat influence on the different areas of accelerated armatures, having the physical nonhomogeneities, has been received. The areas, subjected to the most power influence, in which the armature destruction is possible, have been determined. The study of influence of the short circuit at the rails front part on the field distributions have been conducted.
