METHODS FOR MAKING A TURBINE BLADE

A method for making a turbine blade (30) involving casting an internal skeleton (60) having a plurality of internal ribs (64) which form a plurality of open cooling channels (62); applying a filler material (74) to the open cooling channels (62); and applying an outer wall (76) about the internal sk...
