GAS TURBINE ENGINE Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed gas turbine engine contains compressor, combustion chamber, compressor drive turbine and unit connecting shafts of turbine and compressor with threaded bushing. Said bushing is installed inside turbine shaft which is placed on splines inside compressor shaft. Nut with inner ring projection is installed on threaded shank of bushing. Nut is pressed to ring projecting of turbine shaft by means of outer and inner spherical rings. Directions of threads on front radial projection and shank of bushing coincide. Adjusting rings are installed between front radial projection of bushing and turbine shaft, and also between shank of bushing and inner ring projection of nut. Invention makes it possible to increase efficiency and improved reliability of gas turbine engine by bringing to minimum radial clearances between stator and rotor of turbine owing to dispensing with intermediate members in unit connecting turbine and compressor shafts. EFFECT: improved reliability and efficiency. 2 dwg
