Abstract

The blades are welded individually or as a crown with a release groove in the area of the weld line root and situated peripherally in the plane of the weld to constitute an anular channel connected (a) via inclined cooling air inlet holes to the surface of the rotor and (b) via other cooling channels to further cooling channels disposed in the inclined holes to ensure that they are cooled internally. Esp., the inclined holes are uniformly distributed over a partial circle of the rotor and each is associated with a blade.
