The Velocity and Efficiency Limiting Effects of Magnetic Diffusion in Railgun Sliding Contacts

Abstract

The authors identify and characterize a velocity and efficiency limiting effect called contact velocity skin effect (VSEC) which occurs in the interface of a railgun's sliding contact. Despite enormous contact forces, the armature will remain separated from the rail by a thin adsorbed layer, on the order of 10 to 15 angstroms in this investigation… (More)
