ONE-SHAFT GAS-TURBINE PLANT Russian patent published in 2002 - IPC

FIELD: mechanical engineering; gas- turbine plants. SUBSTANCE: proposed one-shaft gas-turbine plant has intake device, compressor, combustion chamber, multistage turbine including cantilever rotor with hollow shafts and solid disk last in direction of gas flow. At least one disk with central hole and intermediate disks placed in between are arranged in turbine rotor before solid disk. Rotor solid disk is secured in central space of rotor shaft through intermediate splined bushing by means of clamping bolt. EFFECT: improved reliability of plant owing to prevention of resonance oscillations of rotor in working range. 3 dwg
