Abstract

A compressor 12 of a gas turbine system 10 includes at least one inlet row having a plurality of inlet guide vanes. Also included is at least one stator row 14 having a plurality of stator vanes. Further included is a first actuation mechanism 32 operably connected to the at least one stator row 14 , wherein the first actuation mechanism is configured to positionally manipulate the at least one stator row 14. Yet further included is a second actuation mechanism 34 operably connected to the at least one stator row, wherein the second actuation mechanism is configured to positionally manipulate the at least one stator row.
