Abstract (de)

Die erfindungsgemäßen Vorrichtungen dienen der Führung eines Kühlfluides 230 in einer gekühlten Schaufel 210 einer Turbomaschine, insbesondere einer Gasturbine. Die Schaufel 210 weist hierbei zumindest einen in der Schaufel verlaufenden Kühlkanal 213 auf Erfindungsgemäß ist zumindest ein Einschubelement 220 in zumindest einer Aussparung 221 der Schaufel 210 angeordnet. In einer bevorzugten Ausführung der Erfindung grenzt das in der Aussparung 221 angeordnete Einschubelement 220 unmittelbar an die Deckwand 212 und/oder zumindest eine Seitenwand 211 der Schaufel an. Ferner ist in dem Einschubelement zumindest ein Strömungskanal 222 angeordnet, der bevorzugt aus einer in dem Einschubelement 220 angeordneten Nut und der unmittelbar angrenzenden Deckwand 212 und/oder Seitenwand 211 gebildet wird. Der Strömungskanal 222 ist mittels zumindest einer Öffnung 223 mit dem Kühlkanal 213 verbunden. Darüber hinaus strömt das dem Strömungskanal 222 zugeführte Kühlfluid 230 durch eine Durchlaßöffnung 224 in der Deckwand 212 und/oder der Seitenwand 211 in die die Schaufel umströmende Hauptströmung ab. Eine typische Ausführung der Erfindung ist in Figur 2 dargestellt. <IMAGE>
