Abstract
An integrated system for controlling the positioning of a rotating rotor within a compressor to enhance the performance of a gas turbine engine. The rotor being attached to a rotating shaft that is coupled to the compressor housing by a magnetic bearing system. The magnetic bearings support and position the rotor within the high speed tubomachine. During operation of the compressor the magnetic bearings non-axially position the rotor relative to the compressor housing to provide compressor instability control. By non-axially displacing the rotor relative to the compressor housing there is a resulting local disturbance to the fluid flow field, which in turn serves as the disturbance to alter the dynamics of the aerodynamic system and displace the compressor surge line.
