Zusammenfassung:Provided is a method for casting a turbine blade including a blade root, a blade extending in the radial direction from the blade root, and a hollow chamber that passes through the turbine blade in the radial direction from the blade root up to the free end of the blade, wherein the method is carried out using a casting molding defining an outer surface of the turbine blade and using a core accommodated in the casting mold and aligned with positioning means, wherein at least one second core is accommodated in the molding part and aligned with positioning means, wherein the first core and the second core are spaced at a distance from one another and behind one another in the radial direction in the casting mold in such a way that a gap is formed between said cores.
