I am having difficulty finding information on the benefits of improved surface finish on airfoils in gas turbine engines (ie. fan blades and compressor blades and vanes). Also, someone has suggested that there may be an optimum limit (around 12 micro-inches) for airfoils beyond which SFC won't improve. I have tried AIAA but without much success - does anyone have any ideas where such information can be obtained ? Are any of the airlines trialing processes such as Rem Chem and/or Rosler vibratory finishes for the SFC benefits ?
