Loading Noise Prediction Using Experimental Data from HELINOISE Test Campaugn at DNW

Exploiting the aerodynamic and acoustic data-base provided by HELINOISE experimental program, numerical prediction of rotor noise signatures is performed for different flight conditions. The data-fitting problem for blade airlod reconstruction is addressed and solved with different interpolating models. The comparisons between experimental and numerical results are presented in time domain, through the acoustic pressure time histories visualization.
