Abstract

It is noted that electrical contacts have not been experimentally investigated at velocities above a few hundred meters per second. The authors describe a ballistic technique which can be used to measure friction coefficient and contact resistance at velocities up to several kilometers per second (i.e. at railgun armature operating conditions). The theoretical basis of the technique is described, and the experimental hardware is presented
