ROTOR WORKING WHEEL OF HIGH-PRESSURE COMPRESSOR OF GAS TURBINE ENGINE Russian patent published in 2018 - IPC F01D5/30 F04D29/34 F01D5/32 

FIELD: machine engineering.

SUBSTANCE: rotor wheel of the high-pressure compressor of the gas turbine engine comprises a disc with annular groove and blades. A gap is formed between the opposite edges of the groove. At least one mounting groove is made in the opposite edges of the disc annular groove. The roots of the blades are mounted in the disc annular groove along the circumference, the blade root lateral surfaces contact the walls of the annular groove. The inserts with locks are installed in the annular groove. At least one control blade is mounted in the mounting groove between two adjacent inserts, which contact side surfaces of the root are directed towards said inserts and installed in grooves made in adjacent ends of the latter. Between adjacent end faces of inserts and blade roots, there are gaps that equal or larger in width than the distance at which the side contact surface of the counter blade root enters the groove in the insert end.

EFFECT: simplified of mounting, dismounting of any blade in the rotor wheel of the high-pressure compressor rotor of the gas turbine engine.
