Mean Stator Loading Effect on the Acoustic Response of a Rotating Cascade
Discrete-frequency tones generated by unsteady blade row interactions are of particular concern in the design of advanced turbine engines.With a rotor-stator mounted in a duct, only certain specific spatial modes are generated by the rotor-stator interaction, where the generated modes are a function of the number of rotor blades and stator vanes.
