This study applies aerodynamic mistuning using different pattern with circumferentially varying stagger angles of the inlet guide vanes. The experimental investigation is carried out at the Transonic Compressor Darmstadt, using a 1.5-stage modern fro
The aeroelastic effects during stall inception in modern axial compressors have been a research focus for decades and yet are not fully understood. Experimental investigations, conducted at the 1.5-stage transonic compressor test rig at TU Darmstadt,
