Clean Sky 2 Call for Proposals 02 · Experimental characterization of turbulent pressure fluctuations on realistic Contra-Rotating Open Rotor (CROR) 2D airfoil in representative high subsonic Mach number.

Specific Challenge:The prediction of Open Rotor broadband noise requires boundary layer turbulence statistics that are not available today in the literature at the high subsonic relative Mach number encountered by the blades. High fidelity wind tunnel tests shall be performed to fill this lack. Ple…
