Abstract
Provided is a rotor system including: a rotating shaft structure including a shaft and a thrust disc formed in a radial direction of the shaft; at least one journal air bearing including a journal bearing support which is made of a rigid body to support a load applied to the shaft by air, a journal spring which encloses an outer surrounding surface of the journal bearing support to provide a elastic support force to the journal bearing support, and a journal damper which encloses the outer surrounding surface of the journal bearing support to dissipate energy from vibration applied to the journal bearing support; and at least one thrust air bearing including a thrust bearing support which is made of a rigid body to support a load applied to the thrust disc by air, a thrust spring which is positioned on one surface of the thrust bearing support to provide a elastic support force to the thrust bearing support, and a thrust damper which is positioned on one surface of the thrust bearing support to dissipate energy from vibration applied to the thrust bearing support.
