FIELD: engines and pumps.
SUBSTANCE: invention relates to gas turbine engines, particularly, to weldless joint of discs in compressor rotor. Gas turbine engine compressor rotor (1) comprises shaft (8) with coupling nut (10) ahead of front impeller (6) and conical shell ring (7) coupled with said shaft (8) behind the rotor. Shaft (8) is a solid body between said coupling nut (10) and turbine rotor flange joint (11) and integral with conical shell ring (7). Mid wheel (12) is arranged behind the front impeller (6) and made integral therewith or welded thereto.
EFFECT: higher reliability of the rotor, lower labour input at its production.
