    Abstract

    A proposal - for novel fabrication of cooled blades is proposed . This involves only well established processes such as electron beam welding and electrochemical milling . The idea is to form grooves on a solid blade and then attach a thin skin around it by means of electron beam welding. Theoretical analysis and preliminary experiments have shown greatly improved performance of such a cooling system, which can be modified to include film cooling, multipass and impingement cooling . The scope of the project includes development of blades upto demonstrating running in a gas turbine engine.
