GAS-TURBINE ENGINE Russian patent published in 2004 - IPC

FIELD: mechanical engineering; gas-turbine engines. SUBSTANCE: proposed gas-turbine engine contains compressor, combustion chamber and compressor drive turbine. Cantilever rotor of compressor is installed in front radial-thrust and rear radial bearings. Bearing supports are secured on inner housing of combustion chamber. Threaded bushing is installed between compressor and turbine shafts. Ratio of distance between bearings to value of axial clearances between stator and rotor in seals of radial bearing support is 30-150. EFFECT: improved reliability owing to prevention of axial contact of stator and rotor at transient duties. 4 dwg
