Abstract
A blading for a turbomachine, particularly for a gas turbine, wherein thickened areas and depressions formed and disposed on a lateral wall having a plurality of blades such that at least one depression is disposed on a blade pressure side and at least one thickened area is disposed on a blade suction side for each blade of the plurality of blades.
Claims10
A blading for a turbomachine in which a lateral wall has a plurality of blades, the blading comprising:
- at least one depression disposed on a blade pressure side and at least one first thickened area disposed on a blade suction side for each blade of the plurality of blades;
- and
- a pair of adjacent blades selected from the blades;
- a second thickened area extending from the respective blade suction side of a first one of the pair of blades to the respective blade pressure side on a second one of the pair of blades, the second thickened area being in a half of the blading adjacent to an outlet side;
- wherein the second thickened area is defined by a plurality of isolines that measure a height of the lateral wall at a plurality of points on the lateral wall in a direction orthogonal to the lateral wall;
- wherein each isoline of the second thickened area has a first end and a second end;
- the first end terminating at the respective suction side of the first one of the blades, and the second end terminating at the respective pressure side of the second one of the blades.
A manufacturing method for a blading of a turbomachine having at least one reshaping and/or at least one cutting treatment such that thickened areas and depressions are formed in a lateral wall having a plurality of blades, each blade having a respective pressure side and a respective suction side, comprising the steps of forming at least one depression selected from the depressions on the respective blade pressure side and forming at least one thickened area selected from the thickened areas on the respective blade suction side for each blade of the plurality of blades;
- and
- forming a second thickened area between a pair of adjacent blades selected from the plurality of blades so that the second thickened area extends from the respective blade suction side on a first one of the pair of blades to the respective blade pressure side on a second one of the pair of blades, the second thickened area being in a half of the blading adjacent to an outlet side;
- wherein the second thickened area is defined by a plurality of isolines that measure a height of the lateral wall at a plurality of points on the lateral wall in a direction orthogonal to the lateral wall;
- wherein each isoline of the second thickened area has a first end and a second end;
- the first end terminating at the respective suction side of the first one of the blades, and the second end terminating at the respective pressure side of the second one of the blades.
