FIELD: aircraft and ground-based gas-turbine engines.
SUBSTANCE: compressor has rotor braced by means of front and rear nuts and provided with disks mounted through splines on shaft, as well as outside radial-thrust bearing with inner ring and shift-mounted packing members secured in position with aid of fastening nut of bearing inner ring. Novelty is that axial play over rear nut is 0.1 - 0.4 mm and that ratio of distance between front and rear nuts to axial play over rear nut thread L/δ = 1000 - 15 000.
EFFECT: enhanced operating reliability of compressor radial-thrust bearing.
