Patent number: 10408233Abstract: 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.Type: GrantFiled: January 25, 2017Date of Patent: September 10, 2019Assignee: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventor: Thomas Klauke

Publication number: 20180372119Abstract: A method for selecting a mistuning pattern of a turbomachine rotor disk includes providing information items relative to boundary conditions of a rotor disk excitation by forced vibrations; providing a reduced-order model of the rotor disk; producing a multiplicity of mistuning patterns of the rotor disk by entering the information items and the reduced-order model into a multi-objective optimizer and producing the mistuning patterns by the multi-objective optimizer while optimizing stability of the system in relation to self-excited vibrations while simultaneously optimizing stability of the system relative to forced vibrations. For each mistuning pattern produced, the reduced-order model is applied to a rotor disk, which implements the produced mistuning pattern, and the properties of this rotor disk are determined in view of self-excited vibrations and in view of forced vibrations. One of the mistuning patterns is selected for implementation.Type: ApplicationFiled: June 22, 2018Publication date: December 27, 2018Inventors: Felix FIGASCHEWSKY, Jens NIPKAU, Thomas KLAUKE, Arnold KUEHHORN, Bernd BEIROW

Patent number: 8171632Abstract: In the manufacture of integrally designed rotor wheels (BLISKs), the natural frequency of each blade is measured after forming by conventional shaping methods and the respective blade mass and its divergence from the smallest blade mass is calculated therefrom. The mass of each blade exceeding the smallest blade mass is removed by means of an etchant, so that all blades have essentially corresponding thickness, chord length, mass and natural frequency and are evenly loaded in operation. BLISKs manufactured in this way feature a long service life.Type: GrantFiled: December 8, 2008Date of Patent: May 8, 2012Assignee: Rolls-Royce Deutschland Ltd & Co KGInventors: Arnold Kuehhorn, Thomas Klauke
