FIELD: machine engineering.
SUBSTANCE: rotor wheel of the high-pressure compressor of the gas turbine engine comprises a disc with an annular groove on its outer surface. Shanks of blades with contact conical surfaces relative to longitudinal axis of a disc are mounted in the annular groove through mounting grooves. The shanks are fixed in circumferential direction by means of inserts with retainers installed in the annular groove. The mounting grooves correspond to the number of blades and made in one of the edges of the annular groove. The annular groove is in the side wall of the annular groove on the side of the mounting groove. Annular segments are installed in the annular groove for their axial displacement up to the contact with tension with shanks of the blades along the conical surfaces relative to the longitudinal axis of the disc by fixing each of the annular segments relative to adjacent inserts.
EFFECT: inventionmakes it possible to increase manufacturability and maintainability of the compressor rotor due to simplified mounting and dismantling blade in said rotor working wheel.
