#CMT# #/CMT# The method involves forming an integral blade ring (4) by connecting adjacent blades (6) in a blade root region by friction stir welding. The integral blade ring is attached at a rotor hub (8) by friction stir welding, where the final processing of a rotor disk (1) is carried out. A welding tool is attached radially inside at blade roots (12) with radially outward facing shoulder surface for welding the blade roots. The welding tool is moved in longitudinal direction of the blade root. #CMT#USE : #/CMT# Method for manufacturing an integral bladed rotor disk of integral bladed rotor of fluid flow engine (all claimed), such as aircraft engine. #CMT#ADVANTAGE : #/CMT# The method involves forming an integral blade ring by connecting adjacent blades in a blade root region by friction stir welding, where the integral blade ring is attached at a rotor hub by friction stir welding, and hence ensures simple and weight-optimized manufacturing of rotor disk, which increases efficiency of fluid flow engine, where the mechanical and thermal stability of the rotor disk is increased. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a rotor disk. 1 : Rotor disk 4 : Integral blade ring 6 : Blades 8 : Rotor hub 12 : Blade roots. |
