Abstract

The source distribution in the dual jets of a 1:10 scale jet engine model was investigated in a large anechoic facility. A linear microphone array was used to record the data and the analysis was performed with the SODIX method, an optimization technique that fits a model distribution of sound sources with non-uniform directivity to the measured cross spectral matrix. Configurations with a plain secondary nozzle and a secondary nozzle with a serrated trailing edge were investigated with and without a wing installed above the engine. The results show that the SODIX method is able to resolve the different source distributions of the jet with the plain and the serrated nozzle as well as the additional sources that occur when a wing is installed.
