Abstract
An improved type wear protection system for a turbine engine rotor and blade, in which a multilayer clad shim is interposed between a dovetail portion of a blade and the dovetail slot portion of a rotor, is described. The shim, preferably comprised of surface layers of phosphor bronze and a center layer of austenitic stainless steel, is especially effective in preventing fretting damage to titanium engine components.
