Abstract

Anordnung zur Laufspaltoptimierung für Turbomaschinen in Axialbauart durch Steuerung bzw. Regelung des laufspaltrelevanten Innendurchmessers mindestens einer einen Laufschaufelkranz umschließenden Statorstruktur. Die Statorstruktur weist einen geschlossenen Innenring, einen zu diesem konzentrischen und radial beabstandeten Außenring sowie mehrere, den Innenring mit dem Außenring integral verbindende, relativ zur Radialrichtung in Umfangsrichtung geneigte Stege auf. Die Anordnung umfasst eine Verstelleinrichtung zur Verdrehung des Innenrings relativ zum Außenring unter elastischer Veränderung des laufspaltrelevanten Innendurchmessers.
