Abstract (en)
The turbine has guide vanes (14) fastened to a guide vane holder (48) of a guide vane support (16) by dovetail joints (34), which are aligned parallel to a turbine axis. The holder is movably mounted around an axle (50), which is tangential to a radius around the turbine axis. Each guide vane is attached to a combustion chamber (4). The chamber includes a thermal shield (38), which is arranged in a radial direction in an extent of the joints. The shield forms a wall (42) of a groove (44) in which a spring is arranged. A brush seal (56) is arranged between the holder and the support.
Abstract (de)
Eine Gasturbine (1) mit einer Brennkammer (4), einer Anzahl von Leitschaufelreihen und einem Leitschaufelträger (16), soll unter Beibehaltung eines besonders hohen Wirkungsgrades den Austausch von Leitschaufeln weiter vereinfachen und somit für eine besonders kurze Reparaturdauer ausgelegt sein. Dazu ist eine Anzahl von Leitschaufeln (14) mittels einer parallel zur Turbinenachse (9) ausgerichteten Schwalbenschwanzverbindung (34) am Leitschaufelträger (16) befestigt.
