FIELD: engines and pumps.
SUBSTANCE: invention relates to machine building and can be used in production of gas turbine drives of gas compressor plants. Proposed turbo unit comprises drive engine with engine mount frame and supercharger arranged on common frame support surfaces. Supercharger shaft is rigidly and directly coupled with drive engine free turbine shaft. Free turbine shaft thrust bearing seat accommodates single thrust bearing for engine free turbine and supercharger shafts. Engine free turbine exhaust scroll is rigidly coupled with supercharger housing. Single bearing housing is furnished with heat insulator casing.
EFFECT: higher reliability, improved operating performances, lower production costs.
