Abstract

Die Erfindung betrifft eine Aufhängung einer ringförmigen Gasturbinen-Brennkammer im Austrittsbereich derselben an einer Gehäusewand, über eine sich an die äußere Brennkammerwand anschließende, ringförmige, geknickt ausgebildete Armstruktur, die in Bezug auf die Gasturbinen-Längsachse einen äußeren und einen inneren Schenkel aufweist. Erfindungsgemäß schließt sich an den äußeren Schenkel ein Flansch an, der über ein lösbares Verbindungselement fest mit der Gehäusewand verbunden ist. Bevorzugt weisen beide Schenkel über dem Umfang gleichartig verteilt angeordnete, schwalbenschwanzförmige Durchbrechungen auf, deren engste Abschnitte der Knicklinie der Armstruktur zugewandt und zur Knicklinie hin offen sind, so daß zwischen jeder Durchbrechung im äußeren Schenkel und der benachbarten Durchbrechung im inneren Schenkel eine Verbindungslücke vorliegt. Hierdurch ergibt sich eine Aufhängung nach Art einer Blattfeder.
