A first thrust bearing includes a first electromagnet and a first member. A second thrust bearing includes a second electromagnet and a second member. A magnetic force generated by the first electromagnet and the second electromagnet, and dynamic gas pressure generated by the first member and the second member due to rotation of a rotating shaft support an axial load of the rotating shaft.

Bearing structure

A gas turbine rotor includes a first rotor and a second rotor. The first rotor includes a compressor impeller, a turbine wheel, and a shaft. The turbine wheel has a common rotational axis with the compressor impeller. The shaft connects the compressor impeller to the turbine wheel. The second rotor is an electric generator rotor and defines an inner hollow space. The shaft includes an insertable portion disposed in the inner hollow space of the second rotor.

Gas turbine rotor and gas turbine generator

A disclosed micro gas turbine system includes a micro gas turbine apparatus and an extracting cycle apparatus. The micro gas turbine apparatus includes a first compressor, a burner, and a first turbine. The first turbine expands a combustion gas generated by the burner. The extracting cycle apparatus includes a second compressor and a second turbine. The second compressor receives a flow of extracted air that is generated by extracting a part of a working fluid discharged from the first compressor. The second turbine expands the working fluid discharged from the second compressor. The working fluid discharged from the second turbine cools down the first turbine.

Micro gas turbine system

A turbine nozzle according to the disclosure is a turbine nozzle that is used in a radial turbine and includes a ring-shaped hub, a plurality of nozzle vanes that are arranged at equal angular intervals on the hub, and a flow path that is formed between the nozzle vanes. The flow path includes a throat that has a smallest flow path cross-sectional area with respect to a flow direction of working fluid. On a downstream side of the throat with respect to the flow direction, the flow path cross-sectional area increases. Heights of the nozzle vanes on the downstream side of the throat with respect to the flow direction are greater than heights of the nozzle vanes in the throat and gradually increase from an upstream side toward the downstream side with respect to the flow direction.
