Abstract:

One of the research objectives of the Hypervelocity Launch group during 1997 was to understand armature wear, with the eventual goal of developing a predictive model. To this end we conducted sixteen experiments to measure wear at various conditions. This report describes the first ten experiments which directly measured wear in a typical C-shaped railgun armature. Section 2 of the report describes the objectives and our state of understanding at the outset of the research. We also comment on some prior work in related areas. Section 3 describes the techniques developed for making in-bore wear measurements. Section 4 summarizes the first ten experiments. Section 5 presents a physical interpretation of the data our conclusion is based in part on the results of the mechanical wear tests, even though these are not discussed in detail in this report. Four appendices following Section 5 present the data from the experiments in a form that can be used to test models of armature wear.
