Description

technical field

[0001] The present invention relates to a method for manufacturing an integrally bladed rotor, in particular a gas turbine rotor, and the rotor itself. Background technique

[0002] A gas turbine rotor with integrally mounted blades is called a Blisk or Bling, depending on whether there is a rotor or rotor support with a disc-shaped or annular cross-section (hereinafter referred to as the rotor base) . Leaf disc is the abbreviation of disc with blades, and leaf ring is the abbreviation of ring with blades.

[0003] It is known from the prior art that gas turbine rotors with integrally mounted blades are produced in one piece by milling, which is of course very complex and expensive, so this method is only suitable for relatively small gas turbine rotors.

[0004] An additional method used in large rotors is friction welding. In this case, the rotor base body and the blades are produced separately and then friction welded to each other, in particular by lin...
