  • Aerodynamical and Structural Analysis of Operationally Used Turbine Blades 
    Schwerdt, Lukas; Hauptmann, Thomas; Kunin, Artsem; Seume, Jörg R.; Wallaschek, Jörg; Wriggers, Peter; Panning-von Scheidt, Lars; Löhnert, Stefan (Amsterdam : Elsevier BV, 2017)
    This paper presents an integrated methodology for the analysis of operationally-used turbine blades, incorporating aerodynamic and multiple structural simulations. In jet engines, blade rubbing and erosion lead to deviations ...
  • High order sensitivity analysis of a mistuned blisk including intentional mistuning 
    Pohle, Linus; Tatzko, Sebastian; Panning-von Scheidt, Lars; Wallaschek, Jörg (Warsaw : Polish Society of Theoretical and Allied Mechanics, 2017)
    Small deviations between turbine blades exist due to manufacturing tolerances or material inhomogeneities. This effect is called mistuning and usually causes increased vibration amplitudes and also a lower service life ...
  • Spatial dynamics of tuned and mistuned bladed disks with cylindrical and wedge-shaped friction dampers 
    Panning, Lars; Sextro, Walter; Popp, Karl (London : Hindawi Limited, 2003)
    One of the main tasks in the design of turbomachines like turbines, compressors, and fans is to increase the reliability and efficiency of the arrangement. Failures due to blade cracks are still a problem and have to be ...
