VSV actuation arrangement

An actuation arrangement for effecting actuation of a variable stator vane pivotally mounted on a tubular casing, said actuation arrangement comprising:

• an actuator connector connected to the variable stator vane via an actuating lever;
• an anchor fixedly mounted relative to the circumference of said tubular casing;
• an actuator;
• and
• a belt having a proximal end affixed to the actuator and a distal end affixed to the anchor,
• wherein the actuation arrangement further comprises a movable pulley movable relative to said tubular casing and connected to the actuator connector, and wherein the belt has a loop portion provided between the proximal and distal ends which loops around the movable pulley, the loop portion for transferring forces generated in the belt by the actuator to the movable pulley to effect movement of the movable pulley and thereby the actuator connector towards the anchor to effect actuation of the variable stator vane via the actuating lever.
