Abstract

Eine Schaufel (1) für eine Gasturbine umfasst eine Spitzenkappe (4) und eine Anstreifkante(6) und Kanäle (15, 25) für ein Kühlfluid, die sich von einem Hohlraum (5) zur Anstreifkante (6) erstrecken. Gemäß der Erfindung weist die Anstreifkante (6) eine Aushöhlung (16) auf, die sich von einem Halbraum (9) in die Anstreifkante(6) erstreckt, so dass der Kühlkanal in einen ersten und einen zweiten Teil (17, 18) mit einer Austrittsöffnung (11') in der Aushöhlung (16) beziehungsweise mit einer Austrittsöffnung (11) auf der Spitzenkrone (8) unterteilt wird. Falls die Austrittsöffnung (11) auf der Spitzenkrone (8) blockiert wird, kann das Kühlfluid durch die zusätzliche Austrittsöffnung (11') in den Halbraum(9) strömen und die Anstreifkante (6) kühlen.
