Recent Progress in Turbine Blade and Compressor Blisk Regeneration
Procedia CIRP, 2014 The regeneration process of jet engines is a highly complex, expensive and time-consuming. Especially the regeneration of high pressure turbine blades and compressor blisks are at the border of what is technically feasible. These components are highly loaded and thus substantial wear occurs.
