Abstract

Die Erfindung bezieht sich auf eine Spindelkontrollvorrichtung für eine Gasturbine mit zumindest einer Reihe von verstellbaren Schaufeln 2 sowie mit einer an eine Schaufelreihe angrenzenden, gasumströmten Fläche 4, dadurch gekennzeichnet, dass die Fläche 4 im Wesentlichen in Form eines Kugelflächenrings ausgebildet ist und gleichzeitig eine Verengung des Gaskanals mit einer aerodynamisch günstigen Form des Ringraumes erreicht wird.
