Abstract
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.
Claims2
Thermally highly stressed, cooled component in form of an integral single-piece element, such as a turbine engine blade, comprising a centrally arranged supporting core of a solid material;
- plurality of short radially projecting ridges extending from said core;
- an outer shroud carried by said ridges concentrically enveloping the supporting core, said shroud being made of a foamed through-porous material, and said supporting core, ridges, and outer shroud comprised of ceramic material cast in a single piece.
