Abstract: Radial turbine wheels designed as blade integrated disks (blisk) are widely used in various industrial applications. However, related to the introduction of exhaust gas turbochargers in the field of small and medium sized ...

Abstract: The forced response of an E3Etype high pressure compressor (HPC) blisk front rotor is analyzed with regard to varying mistuning and the consideration of the fluidstructure interaction (FSI). For that purpose, a reduced ...

Abstract: The forced response of the first rotor of an engine 3E (technology program) (E3E)type high pressure compressor (HPC) blisk is analyzed with regard to varying mistuning, varying engine order (EO) excitations and the ...

Abstract: Objective of this paper is to analyze the consequences of borescope blending repairs on the aeroelastic behavior of a modern high pressure compressor (HPC) blisk. To investigate the blending consequences in terms of ...

Abstract: Rotor blade vibrations observed in the Darmstadt transonic compressor rig are investigated in this paper. The vibrations are nonsynchronous and occur in the near stall (NS) operating region. Rotor tip flow fluctuations ...
