What is it about?
We did simulations to verify a simple model to understand how aerodynamic damping changes with several parameters such a frequency, mode-shape and Mach number

Why is it important?
Never was explained before analytically why aerodynamic damping in turbomachinery increases linearly with the vibration frequency
Perspectives
I think this reference will become a classic in aeroelasticity textbooks
