Definitions
- the impingement cooling element 28 is essentially ceramic. That is, the impingement cooling member 28 has a ceramic as a main component. It is therefore not a metallic impingement cooling element with a ceramic coating. If necessary, the ceramic can also have stiffening elements such as fibers or similar structures.
- the impingement cooling element 28 inserted into the cavity 24 is located at a distance from the blade wall 20, 22 to be cooled. Thus, between the blade wall 20, 22 to be cooled and the impingement cooling element 28, a gap 30 is provided, through which the coolant flowing inside the ceramic is provided by means provided in the impingement cooling element 28 Openings 32 can radiate out.
- the coolant flowing out of the impingement cooling openings 32 impinges substantially perpendicularly on the inside of the wall 20, 22 of the turbine guide vane to be cooled.
- the wall 20, 22 is cooled in a known manner. Subsequently, the coolant present in the intermediate space 30 can flow out of this.
- the ceramic is formed as a porous ceramic, so that the porosity makes it possible to form the cooling air jets impinging on the wall 20, 22 to be cooled.
