Analysis of the Armature-Rail Interface in Solid Armature Railguns: Collected Reports of Professor L. C. Woods Volume II (November 1996 - May 1997)
Abstract
A second collection of reports written by L.C. Woods for the Institute for Advanced Technology (IAT), University of Texas at Austin, investigating the liquid metal interface between a solid armature and conducting rail of an electromagnetic launcher. The first report has multiple objectives: determine the rate at which the armature is melted by viscosity to find the thickness of the deposited layer of aluminum; investigate the stability of the liquid layer under the viscous and electromagnetic forces; and derive an expression for the solidification time. The second report continues the work of the first in determining how the total electromagnetic force is distributed over the rear of the armature and thus the force acting on the liquefied armature material at the rail/armature interface. The third report explores the observations that can be made to test the melt-wave model. The final report describes the experimental conditions and type of instability that may be involved when both the rails and the armature are made of aluminum.
