Abstract

Vorrichtung (3) zum Einspannen von beschaufelten Rotorscheiben (4, 6, 9) eines Strahltriebwerkes, das im Wesentlichen einen axialen Verdichter mit mehreren beschaufelten Rotorscheiben (4, 6, 9), mindestens einen Turbinenabschnitt, mindestens eine Welle und mindestens einen Zuganker (12, 47) umfasst, wobei mindestens zwei beschaufelte Rotorscheiben an der Verdichtereintrittsseite (2) als Blisks (6) ausgebildet sind, die jeweils eine einteilige Ausführungsform einer Rotorscheibe mit am Umfang verteilten Laufschaufeln (5) bilden. Um eine Vorrichtung zum Einspannen von Blisks zur Verfügung zu stellen, die leicht montierbar und demontierbar ist, sieht die Erfindung vor, dass die Blisks (6) mittels des Zugankers (12, 47) lösbar eingespannt und die anderen Rotorscheiben (4, 9) separat und unabhängig vom Zuganker (12, 47) fest miteinander verbunden sind.
