초록

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...

청구항

A method for enhancing the operating stability of a compressor having a rotor within a compressor housing, comprising: rotating the compressor rotor; and non-axially displacing the rotating compressor rotor with respect to the compressor housing, said non-axially displacing is provided to reduce circumferential pressure non-uniformities. In combination: a gas turbine engine; and a compressor within said engine for pressurizing a fluid, comprising: a mechanical housing; a shaft rotatable within said housing; at least one rotor connected to said shaft, sai...
