Abstract

Es ist eine Gasturbinenanordnung offenbart, welche einen Rotor, einen Heissgaskanal, durch welchen ein Heissgasstrom (12) während des Betriebs der Gasturbine strömt, mindestens eine erste Reihe von Turbinenschaufeln (1), welche ein Schaufelblatt (3) mit einer Saug- und einer Druckseite (11, 10) und eine Plattform (4) aufweisen, und mindestens eine zweite Reihe von Turbinenschaufeln (2), welche in axialer Richtung des Rotors und in Richtung der Heissgase (12) vor der ersten Reihe von Turbinenschaufeln (1) angeordnet sind und ebenfalls eine Plattform (4) aufweisen, umfasst. Zwischen der ersten Reihe von Turbinenschaufeln (1) und der zweiten Reihe von Turbinenschaufeln (2) sind im Bereich der jeweiligen Plattformen (4) mindestens eine Dichtung (5, 6) vorhanden ist, durch welche ein Kühlluftleckagestrom (7) während des Betriebs der Gasturbine austritt. Erfindungsgemäss sind Mittel (8, 9) vorhanden sind, die den Leckagestrom (7) der Kühlluft entlang der Oberfläche der Plattform (4) zur Druckseite (10) der ersten Reihe von Turbinenschaufeln (1) leiten.
