Abstract

Beschrieben wird eine Vorrichtung sowie ein Verfahren zur Kühlung eines Deckbandsegments einer Turbinenschaufel, die einen Schaufelfuß, ein Schaufelblatt mit einer An- und Abströmkante, sowie eine Schaufelspitze mit einem Deckbandsegment in der Form einer Plattform aufweist und die radial von wenigstens einem Kühlkanal wenigstens teilweise durchsetzt ist, der mit wenigstens einem, über eine Austrittsöffnung an der Plattform austretenden Austrittskanal verbunden ist.
Die Erfindung zeichnet sich dadurch aus, dass der Austrittskanal angrenzend zur Austrittsöffnung eine Kanallängsrichtung aufweist, die in Projektion längs zur Turbinenschaufel weitgehend koparallel zur Strömungsrichtung eines die Austrittsöffnung unmittelbar überströmenden, lokalen Strömungsfeldes eines relativ an der Turbinenschaufel vorbeiströmenden Massenflusses verläuft.
