Abstract

Bei einem Gasturbinenrotor mit innenraumgekühlten Schaufelblättern (4) der Turbinenlaufschaufeln und einem mechanischen Dichtungs- und Dämpfungselement zwischen den einander gegenüberliegenden Seitenflächen (6) der benachbarten Schaufelplattformen (7) wird der Spalt gegenüber dem Heißgasstrom zusätzlich aerodynamisch abgedichtet, und zwar mit Kühlluft, die über einen Kühlkanal (9) aus einem Hohlraum (5) der Schaufelblätter in den Spalt zwischen den Seitenflächen (6) geleitet wird.

Figure imgaf001
In a gas turbine rotor with internally cooled blades (4) of the turbine blades and a mechanical sealing and damping element between the opposite side surfaces (6) of the adjacent blade platforms (7), the gap is additionally aerodynamically sealed with respect to the hot gas flow, with cooling air flowing over one Cooling passage (9) from a cavity (5) of the blades is guided into the gap between the side surfaces (6).
