Abstract

Purpose. The establishment of technical features of the preparatory process for isothermal pressing blisks.

Design/methodology/approach.The technical process of manufacturing solid-forging vane wheel (blisks) of gas-turbine engine has a high labor content and low coefficient of metal use. The most promising process for manufacturing such parts is isothermal pressing, which provides a favorable formation of the texture of the material in the body of the disc and blades.

Findings. The estimation of the flow characteristics of the metal in forming blisks from a radial arrangement of the blades using the Deform-3D software complex. The installation and typical stamp for isothermal pressing was developed.

Originality/value. Energy and power parameters and stress-strain state installed at different stages of forming blisks.
