Abstract

Gehäusestruktur in Metallbauweise für den Laufschaufelbereich von axial durchströmten Verdichter- und Turbinenstufen, mit einer geschlossenen, stabilen Außenwand, mit einer mehrfach durch Dehnfugen unterbrochenen, segmentierten Innenwand und mit einer lastübertragenden Verbindungsstruktur zwischen Innen- und Außenwand.
Als Verbindungsstruktur ist eine vielfach unterteilte Hohlkammerstruktur mit einer Vielzahl von dünnen, hochkant auf Innen- und Außenwand stehenden, zumindest großteils direkt zusammenhängenden Wandelementen angeordnet.
Die Hohlkammerstruktur ist mit der Innen- und/oder Außenwand durch Löten verbunden.
