Aeroeleasic Investigation of an Annular Transonic Compressor Cascade: Experimental Results

Peter Ott, Virginie Anne Chenaux, Achim Zanker

A reliable determination of the unsteady aerodynamic loads acting on the blades is essential to predict the aeroelastic stability of vibrating compressor cascades with accuracy. At transonic flow conditions, the vibration of the shock may change the blade ...
