Abstract

Bei einer Plattformkühlanordnung für den der Brennkammer nachgeschalteten Leitschaufelkranz einer Gasturbine sind am Umfang eine oder mehrere parallelen Reihe(n) von kontinuierlich oder in Gruppen angeordneten Kühlluftausblaskanälen (10) angeordnet. Die Kühlluftausblaskanäle sind bezogen auf die Umfangsrichtung (15) in einem Winkel (α) winklig angeordnet, um an der Oberfläche der Plattform (2) eine Wirbelstruktur zu erzeugen, die zum einen die Vermischung der Kühlluftstrahlen (11) mit dem Heißgasstrom (8) vermindert und zum anderen auch die vollständige Kühlung des stromabwärts einer Grenzschichttrennlinie (13) liegenden Bereichs der Grenzschichtablösung (12) bis hin zur Saugseite (14) der benachbarten Leitschaufel (1) gewährleistet.
