Beschreibung
Zusammenfassung:	A pattern (140) for casting a component has a pattern material (144) and a casting core combination (142). The pattern material (144) has an airfoil (146). The casting core combination (142) is at least partially embedded in the pattern material (144). The casting core combination (142) comprises a plurality of metallic casting cores (162A-162E). Each metallic casting core has opposite first and second faces (163-164) and a respective portion along the trailing edge of the airfoil (146). At least two of the metallic cores (162A-162E) have sections offset between a pressure side and suction side of the airfoil (146).
