Abstract

Turbinenschaufeln nach dem Stand der Technik weisen in einem Übergangsbereich zwischen Schaufelblattbereich und Plattform eine Materialanhäufung auf, die schwierig zu kühlen ist.
Eine erfindungsgemäße Turbinenschaufel (1) weist einen inneren Konturverlauf (31) auf, der dem Konturverlauf des äußeren Übergangsbereichs (19) angepasst ist, so dass im wesentlichen eine gleichmäßige Schaufelwanddicke (22) erreicht ist.
