Beschreibung
Zusammenfassung:	A system adjusts positions of gas turbine inlet guide vanes (IGVs) (14) and variable stator vanes (VSVs) (16). The system includes a hydraulic power unit (24) providing a supply of hydraulic fluid, an IGV servo (36), and a VSV servo (38). An IGV cylinder set (28) is provided in fluid communication with the hydraulic power unit via the IGV servo and is connected to the IGVs. A VSV cylinder set (30) is provided in fluid communication with the hydraulic power unit via the VSV servo. The VSVs include multiple stages linked together with a torque shaft (56). The VSV cylinder set is connected to the torque shaft, and the VSV cylinder set effects simultaneous displacement of the stages of the VSVs between a closed position and a fully open position. The IGV servo and the VSV servo respectively control delivery of hydraulic fluid from the hydraulic power unit to the IGV cylinder set and the VSV cylinder set, and the IGV servo and the VSV servo are independently controllable.
