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. Expected duration is about 5 years and cost Rs . 99_92_lakhs_
