Abstract
A gas turbine with an active clearance control system includes a plurality of actuators circumferentially spaced between an inner shroud and an outer casing. The actuators are configured to eccentrically displace the shroud relative to the outer casing. A plurality of sensors circumferentially spaced around the shroud detect a parameter that is indicative of an eccentricity between the rotor and shroud as the rotor rotates within the shroud. A control system in communication with the sensors and actuators is configured to control the actuators to eccentrically displace the shroud to compensate for eccentricities detected between the rotor and shroud.
