Abstract

Die Erfindung betrifft eine Honigwabenstruktur (1), welche an einem Stator einer Gasturbine angeordnet ist und welche den Laufschaufeln der Gasturbine gegenüberliegend angeordnet ist. Die Honigwabenstruktur (1) setzt sich derart aus Blechen (5) zusammen, dass Stege (3) mit doppelter Blechstärke entstehen und einfach ausgeführte Verbindungen (4) zwischen den Stegen (3). Der Winkel (α) zwischen der Umfangsrichtung (2) des Stators und den doppelt ausgeführten Stegen (3) beträgt 5° bis 175°. Dies dient zur Vermeidung von ungünstigen Effekten wie zum Beispiel Überhitzung bei der Reibung an der Honigwabenstruktur (1) der Laufschaufel der Gasturbine.
