Abstract
A major concern in the design process of modern turbomachinery, e.g. aircraft engines, is aeroelasticity. Due to the possible risk of failure of the aircraft engine by cause of highcycle fatigue (HCF), numerical analyses for the estimation of utter and forced response risk are already carried out during the design phase. Therefore, the validation of the aeroelastic toolchain used is an important prerequisit of the design. This paper shows a validation of time-linearized forced response CFD results created with the CFD code TRACE by a comparison with experimental data. The experimental data is collected out on the 1-stage axial compressor test rig at the Institute of Turbomachinery and Fluid Dynamics at the Leibniz Universität Hannover. The amplitude of the blade oscillation is measured with a commercial tip timing system and subsequently compared with the amplitudes of the numerical forced response calculations. The results of the experimental investigations validate the results of the numerical setup for both investigated mode shapes.
