A VARIABLE STATOR VANE ARRANGEMENT FOR AN AXIAL FLOW COMPRESSOR
A variable stator vane arrangement for an axial flow compressor comprises a plurality of stages of variable pitch stator vanes each of which is operated by a respective control ring. The vanes in each stage are connected to the control rings by operating levers. An axially extending member is connec...

| description | A variable stator vane arrangement for an axial flow compressor comprises a plurality of stages of variable pitch stator vanes each of which is operated by a respective control ring. The vanes in each stage are connected to the control rings by operating levers. An axially extending member is connected to each control ring by operating links. The axially extending member is arranged in a plane substantially tangential to each control ring and is movable in the plane substantially tangential to the control rings to change the pitch of the variable pitch stator vanes. Hydraulic rams are provided to move the axially extending member. The hydraulic rams may be operated to give either proportional or non-proportional movement of the variable pitch stator vanes. A controller may use signals from position detectors positioned on the control rings or position detectors positioned on the hydraulic rams together with compressor parameters to control the pitch of the vanes. |
