Air bearing and rotor system

An air bearing comprising:

• a bearing support which is made of a rigid body and is positioned on one side of a rotating shaft structure to support an axial load of the rotating shaft structure by air;
• a spring which is positioned on one surface of the bearing support to provide a elastic support force to the bearing support;
• and
• a damper which is positioned on one surface of the bearing support to dissipate energy from vibration applied to the bearing support.

A rotor system comprising:

• 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 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 form vibration applied to the thrust bearing support.
