Analysis of the Armature-Rail Interface in Solid Armature Railguns: Collected Reports of Professor L. C. Woods (October 1995-June 1996).
Abstract
A collection of reports written by L.C. Woods for the institute for Advanced Technology (lAT), University of Texas at Austin, investigating the liquid metal interface between a solid armature and conducting rail of an electromagnetic launcher as it effects transition and gouging. In the first report, a two dimensional current melt wave model is presented that provides a datum against which observations and numerical modeling can be compared. The second report removes some of the initial assumptions and replaces the ideal model of electrical contact by the contact spot model. The third report replaces the dimensional arguments used in the first report to obtain the scale lengths for the current distributions with a mathematical solution. The fourth report utilizes beam theory to investigate the critical velocity at which rail gouging is likely to begin. Report five provides a description of how one might set up an efficient numerical treatment that allows for both three-dimensional effects and time dependence. The final report concludes with an explanation of the transverse striations that have been observed with aluminum rails.
