Abstract
A support arrangement for a unison ring in a system for varying the angles of attack of compressor vanes in an axial flow gas turbine engine compressor. The support arrangement includes a plurality of struts which provide radial support for the unison ring on the compressor case and a corresponding plurality of eccentric washers disposed between platforms on the struts and an overhanging flange on the unison ring. When the washers are rotated, the positions of the struts are adjusted radially and when the washers and struts are clamped to the unison ring, forces are reacted between the struts and the unison rings through the washers.
