Abstract
In adjusting turbine vanes to control the nozzle area, the unison ring actuates a lever that has one end fixed to the vane casing ring and the vane actuating arm is connected to the lever at a point between the ends to reduce actuating forces required by the unison ring and to permit close tolerance control on the vane angle position.
