Abstract
A rotor in BLISK or BLING design of an aircraft engine, comprising: a rotor disc that, at its radially outer area, forms an annulus which delimits the flow channel of the aircraft engine radially inside; and a plurality of rotor blades that project from the annulus; wherein the rotor disc forms a first structure and a second structure which are arranged at a distance from each other in the radial direction, wherein the first structure and the second structure respectively have an arm that protrudes upstream and/or downstream in the axial direction. An arm of the first structure arranged upstream and an arm of the second structure arranged upstream and/or an arm of the first structure arranged downstream and an arm of the second structure arranged downstream are connected to each other by means of a damping element that comprises an elastomer or is formed from an elastomer.
