Abstract
The invention relates to an airfoil as well as to a method for producing an airfoil for a turbomachine, comprising a leading edge and a trailing edge joined to each other by a suction side and a pressure side and which, in at least one region, extends in a curved manner from an airfoil root to an airfoil tip, wherein the airfoil tip has a squealer tip, which is arranged at the airfoil tip.
Claims12
An airfoil for a turbomachine, comprising:
- a leading edge and a trailing edge joined to each other by a suction side and a pressure side and which, in a least one region, extends in a curved manner from an airfoil root to an airfoil tip, wherein the airfoil tip has a squealer tip, which is arranged along a centroid curve at the airfoil tip, wherein the centroid curve passes through the centroidal axes of the airfoil.
A method for producing an airfoil for a turbomachine, comprising the following steps:
- a) determination of the centroidal axes of the airfoil depending on a blade geometry;
- b) determination of a centroid curve at an airfoil tip depending on the centroidal axes;
- c) determination of an arrangement of a squealer tip depending on the determined centroid curve;
- and
- d) production of the airfoil with a squealer tip in accordance with the arrangement determined in the step c).
