Zusammenfassung:A system, for use in a rotary machine, includes a magnetic actuator (68) configured to adjust a radial clearance (50,52) between a housing (23) and rotary blades (36) via translational movement along a rotational axis. The system includes a controller (70) configured to engage the magnetic actuator (68) to adjust the radial clearance (50,52) in response to feedback.
