Abstract (en)

The blade (10) has a fastening and platform section at which a blade leaf with blade units (28, 30) is attached with a blade leaf point (36). The blade units are connected as a suction side leaf wall (18) and as a pressure side leaf wall (20). The blade units are secured in the area of the blade leaf point against formation of a gap between the blade units by a form closure. The form closure is formed by a hooking unit (39), which is hooked between the blade units. The hooking unit has a bracket (40) with two oppositely lying bracket ends (54, 56), which engage hooks (46, 48).

Abstract (de)

Die Erfindung betrifft eine Turbinenschaufel (10) mit einem aerodynamisch profilierten Schaufelblatt (16), welches aus zwei zusammengefügten Schalenelementen (28, 30) hergestellt ist. Die die saugseitige und die druckseitige Schaufelblattwand (18, 20) bildenden Schalenelemente (28, 30) sind mittels eines Hochtemperatur-Hochdruck-Bonding-Prozesses zusammengefügt worden, die unter Umständen an der Schaufelspitze (36) auseinander klaffen können. Um dies zu verhindern, ist im Bereich der Schaufelblattspitze (36) eine Klammer (40) vorgesehen, welche die beiden Schaufelwände (18, 20) formschlüssig miteinander verhakt.
