Abstract

Die Erfindung betrifft eine axial durchströmte thermische Turbomaschine mit einem Rotor (1) aus einem metallischen Material mit einer ersten Dichte (D1), bei welchem in einer Umfangsnut abwechselnd Laufschaufeln (3, 3') und Zwischenstücke (4) montiert sind. Sie ist dadurch gekennzeichnet, dass die besagten Zwischenstücke (4) aus einem Material mit einer zweiten Dichte (D2) bestehen, welche geringer ist als die erste Dichte (D1). Als Material für die Zwischenstücke (4) sind vor allem intermetallische Verbindungen, vorzugsweise intermetallische γ-Titan-Aluminid-Legierungen oder intermetallische orthorhombische Titan-Aluminid-Legierungen, geeignet, aber auch Titanlegierungen.

The invention relates to an axial flow thermal turbomachinery with a rotor (1) made of a metallic material having a first density (D 1 ), wherein in a circumferential groove alternately blades (3, 3 ') and intermediate pieces (4) are mounted. It is characterized in that said intermediate pieces (4) consist of a material having a second density (D 2 ) which is less than the first density (D 1 ). Intermetallic compounds, preferably γ-titanium-aluminide intermetallic alloys or intermetallic orthorhombic titanium-aluminide alloys, are suitable as material for the intermediate pieces (4), but also titanium alloys.
