Abstract

Die Erfindung betrifft eine axial durchströmte thermische Turbomaschine mit einem metallischen Rotor (1), bei welchem in einer Umfangsnut Laufschaufeln (3) aus einer intermetallischen Verbindung zu einer Schaufelreihe montiert sind. Die Erfindung ist dadurch gekennzeichnet, dass mindestens zwei gleichmässig voneinander beabstandete Laufschaufeln (3') aus einem duktileren Material in der besagten Schaufelreihe zwischen den intermetallischen Laufschaufeln (3) angeordnet sind, wobei die Laufschaufeln (3') aus dem duktileren Material entweder deutlich länger sind als die intermetallischen Schaufeln (3) oder bei gleicher Länge eine andere Schaufelspitzenform als die intermetallischen Schaufeln (3) aufweisen.

Figure imgaf001
The invention relates to an axial turbomachine with a metallic rotor (1), in which in a circumferential groove blades (3) are mounted from an intermetallic compound to a blade row. The invention is characterized in that at least two equally spaced blades (3 ') of a more ductile material are disposed in said blade row between the intermetallic blades (3), the blades (3') of the more ductile material being either significantly longer as the intermetallic blades (3) or the same length have a different blade tip shape than the intermetallic blades (3).
