| description | A system adjusts positions of gas turbine inlet guide vanes (IGVs) and variable stator vanes (VSVs). The system includes a hydraulic power unit providing a supply of hydraulic fluid, an IGV servo in fluid communication with the hydraulic power unit, and a VSV servo in fluid communication with the hydraulic power unit. An IGV cylinder set is provided in fluid communication with the hydraulic power unit via the IGV servo and is connected to the IGVs. The IGV cylinder set effects displacement of the IGVs between a closed position and a fully open position. A VSV cylinder set 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. 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. |
