Assembly method for unitary vaned rotors and device for the damping of vane vibrations

摘要

The method involves assembling a vibration damper unit (25) on blades (8) of disks and welding the disks by friction. The blades of the disks are machined before welding the disks. An additional vibration unit is assembled between the unit (25) assembled on the blades of one disk during the friction welding and a part of a welding machine which is found with respect to the unit (25). - An INDEPENDENT CLAIM is also included for a device for damping vibrations of a blade of a mono-block bladed disk of a compressor of a jet engine.
