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.
