Procedure for the manufacture of a single thermally charged refrigerated component, in particular a shovel for turbine engines

摘要

A thermally highly stressed, cooled component, more particularly, a blade for turbine engines, and a method for manufacturing the blade. A component of the above-mentioned type in which a central supporting core formed of a solid material has connected thereto several short, radially outwardly projecting ridges which, in turn, carry an outer shroud concentrically encompassing the supporting core, and which is made of a through-porous material, whereby the supporting core, ribs, and outer shroud are cast in a single piece.
