Abstract

Strömungsmaschine, insbesondere Verdichter einer Gasturbine, mit Laufschaufeln (11) und Leitschaufeln (12), bei der einzelne oder sämtliche Leitschaufeln (12) als Kühlschaufeln ausgebildet sind. Die Kühlschaufeln (12) weisen Luftführungskanäle (13) auf, die im Bereich der Schaufelspitzen (15) in Ausblaseöffnungen (14) münden. Kühlluft (K) wird durch die Ausblaseöffnungen (14) ausgestoßen und trifft auf eine Rotorwelle (18) mit hoher Geschwindigkeit auf. Die hierdurch erzielbare Kühlwirkung ist optimal und führt darüber hinaus zu einer Anhebung des Verdichterwirkungsgrades und der Pumpgrenze.
