FIELD: engines and pumps.
SUBSTANCE: proposed rotor comprises high-pressure compressor rotor, high-pressure turbine rotor and tube. Said tube is arranged between two air bleeders arranged inside high-pressure compressor rotor. Tube part above high-pressure turbine rotor features OD larger than high-pressure turbine rotor shaft ID by 2-10 mm. Tube part between high-pressure compressor rotor and that of high-pressure turbine features OD larger than high-pressure turbine rotor shaft ID by 2-20 mm Tube is locked at high-pressure turbine rotor shaft against axial displacement and turn about engine axis.
EFFECT: higher reliability of turbo compressor operation.
