TURBO-ELECTRO-GENERATOR Russian patent published in 2011 - IPC F01D15/10 

FIELD: machine building.

SUBSTANCE: rotor consists of metal shaft. Propellers of the compressor and gas turbine with blade units and bearing disks are arranged on this shaft. The stator consists of a stator case, of a turbine nozzle unit and of a compressor outlet diffuser. Bearing-thrust units of the rotor shaft are arranged in the stator of the turbo-compressor. The electro-generator consists of a rotor part with magnet ceramic elements and of a stator part in form of a metallic torus containing current conducting winding. The turbo-compressor also includes a heat regenerator of gases exhausting the turbine. An outlet of the regenerator has an air connection with the inlet of the combustion chamber. The rotor part of the electro-generator is mounted on the shaft of the turbo-compressor between the propellers of the compressor and turbine and consists of segments of a magnetic ceramic casing placed into an internal cavity of at least one toroid casing out of metal alloy. The stator part of the electro-generator with through axial channels is installed in the stator of the turbo-generator. An axial symmetrical distributing cavity is made behind the outlet diffuser of the compressor. The cavity is restricted with the stator case, bearing disk of the compressor propeller and an end of the torus of the stator part of the electro-generator facing the compressor. The outlet from the compressor diffuser and inlet sections of the through axial channels are communicated with this distributing cavity. The outlet sections of through axial channels are communicated with an axial symmetrical collecting cavity restricted with the stator case, bearing disk of the turbine propeller and end of torus of the stator part of the electro-generator facing the turbine. The combustion chamber and the regenerator are encased into a single cavity with inlet and outlet routes. The inlet route is located on the side of the combustion chamber and is communicated with the axial symmetrical distributing cavity, while the outlet route is located in the side of the regenerator and is communicated with the air inlet into the regenerator.

EFFECT: increased reliability and efficiency of turbo-generator.
