Quantification of Aero Damping Influence

This test series uses a modified cascade developed originally for the first ADTurB project and was used to evaluate the relative influence of aerodynamic & mechanical mistuning on the aerodynamic damping and forced response.
Known displacements (torsion & bending) are applied and aerodynamic effects measured. The effects investigated were:
- Frequency mistune - blade movement due to forced response, and steady/unsteady pressure measurements.
- Mode shape mistuning - influence of mode shape variability (amount of torsion/bending per blade) on the aero damping.
- The experimental work was carried out at EPFL
