FIELD: engines and pumps. ^ SUBSTANCE: invention is related to gas-turbine engines, namely, to weldless connection of disks in compressor rotor, and makes it possible to provide unambiguous ensured tightening of rotor (without gaps in joints ) by tightening only by rims. Rotor of gas turbine engine compressor consists of impellers (3) with splines (4) arranged on projecting elements (5) in connection with shaft (8). Compression nut (12) on shaft (8) is installed only on the side of front wheel (6), and thrust conical shell (7) connected to shaft is installed downstream rotor. ^ EFFECT: ensured rotor tightening (without gaps in joints). ^ 4 cl, 2 dwg |
