How Are The Variable Stator Vanes In A Gas Turbine Controlled? The vane actuating apparatus is used to adjust the angle of incidence of a set of variable vanes in the gas turbine engines come with the plurality of the vane actuator levels. They are attached to one end to a respective vane and at the other end to an actuation arrangement for moving the vanes. The stator vane polishing makes the functioning smooth.
Connection Arrangement Each lever has an interlocking arrangement for pivotally connecting the lever in such a way that lever can be removed easily from the vane at the first angular position. It can be retained in interlocking engagement for pivotal movement at second angular position. In a gas turbine, the turbine rotor is turned at high speed
