Kurzfassung
Experimental data from the AWB aeroacoustic wind tunnel of DLR in Braunschweig measured with linear microphone arrays is analyzed using the SODIX method. The data from the European project DJINN for isolated and installed jets is processed in order to achieve a far-field projection of the source directivity based on the near field data using the capability of SODIX to reconstruct a set of equivalent sources with directive radiation on the engine axis that matches the data measured in the near field.
