ABSTRACT:
An improved vane actuation system for a gas turbine engine having adjustable stator vanes in stages between which the engine casing exhibits relative axial and radial thermal growth, the improved system including a pair of platforms on the casing forming therewith three bar link arrangements which automatically compensate for radial and axial thermal growth, rollers on each platform supporting vane actuation rings in centered relationship on the axis of the engine, connectors between the rings and the vane arms which locate the vanes but which permit radial expansion of the arms to accommodate radial thermal growth, a pair of bell cranks on each platform operated remotely and simultaneously, and links between each bell crank and corresponding ones of the rings operative to rotate the rings and, in combination with the rollers, to foreclose translation of the rings in their respective planes.
