WALL OF A STRUCTURAL COMPONENT, IN PARTICULAR OF A GAS TURBINE COMBUSTION CHAMBER WALL, TO BE COOLED BY MEANS OF COOLING AIR

摘要

A wall of a structural component to be cooled by means of cooling air with at least one cooling air channel, which at least in its outflow area is arranged so as to be inclined at an angle with respect to the wall inclined, penetrating the wall from the side at which the cooling air is supplied to the thermally loaded side, characterized in that the cooling air channel has a tubular extension on the side where the cooling air is supplied, wherein the tubular extension is arranged at an angle to the surface of the wall and is supported by means of a rib with respect the surface of the wall, and in particular to an inner gas turbine combustion chamber wall with effusion holes.
