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.

Figure imgaf001
The invention relates to a spindle control device for a gas turbine with at least one row of adjustable blades 2 and with a blade row adjacent, gasumströmten surface 4, characterized in that the surface 4 is formed substantially in the form of a spherical surface ring and at the same time a constriction of the Gas channels with an aerodynamically favorable shape of the annular space is achieved.
