Abstract
Die Erfindung betrifft einen Axialkompressor mit mindestens einer Statorschaufelreihe (18), dadurch gekennzeichnet, dass mindestens eine Schaufel (8) der Statorschaufelreihe (18) als eine rotierende Einheit (6) ausgebildet ist, wobei die rotierende Einheit (6) vollständig um eine Antriebsachse (26) rotierbar ist, und wobei die Antriebsachse (26) im Wesentlichen senkrecht zu einer Axialkompressorrotationsachse (27) ist. The invention relates to an axial compressor with at least one row of stator blades (18), characterized in that at least one blade (8) of the stator blade row (18) is designed as a rotating unit (6), the rotating unit (6) being completely surrounded by a drive axle (6). 26) is rotatable, and wherein the drive axle (26) is substantially perpendicular to an axial compressor rotational axis (27).
