Control of variable stator vanes
Abstract:
In a gas turbine engine having a set of variable stator vanes, a vane actuator ring, and a set of actuator levers linking the vanes to the ring in a one-to-one relationship, an improved manner of linking the vanes to the ring comprises providing a lever of thin sheet material and clamping a trough-shaped end of the lever to a wedge-shaped end of vane stem so that the lever takes up the profile of the end of the stem.
