Abstract

Ein Schaufelblatt (10) enthält eine Vorderkante (12), eine Hinterkante (14), eine Saugseite (16) und eine Druckseite (18), wobei sich mehrere innere Hohlräume (20, 22, 24) innerhalb des Schaufelblattes (10) in Radialrichtung erstrecken, wobei sich ein erster innerer Hohlraum (24) entlang der Hinterkante (14) erstreckt. Die Hinterkante (14) ist mit mehreren entlang dieser angeordneten Kühlmittelaustrittsöffnungen versehen. Mehrere Wirbelgeneratoren sind auf einer Innenfläche der Druckseite (18) und/oder der Saugseite (16) des Schaufelblattes (10) ausgebildet. Die Wirbelgeneratoren sind erfindungsgemäss in einer radial voneinander beabstandeten Anordnung im hinteren inneren Hohlraum (24) angeordnet und erstrecken sich im Wesentlichen parallel zu der Hinterkante (14).
