methods for producing shaped blades turbomacchina with channels through production of turbomacchina and turbomacchine additive, shovels

摘要

A hollow blade (50) for a turbomachine comprises an airfoil portion; the airfoil portion (1) extends longitudinally for a length; the airfoil portion (1) is defined laterally by an external surface; the airfoil portion has at least one internal cavity (54, 55) extending along said length and defined laterally by an internal surface; the airfoil portion has a set of channels (56, 57) extending from the external surface to the internal surface; the openings of said channels (56, 57) on said external surface are aligned along a curved line that reflects an isobar on said external surface; additive manufacturing is particularly effective and advantageous for such blade.
