Kurzfassung
Short review of research activity between DLR, Empa, and TU Braunschweig on aircraft noise assessment, i.e., from single components to large scenarios. Within this joint research initiative, a multi-level, multi-fidelity approach is proposed in order to enable a comprehensive aircraft noise assessment. On the first level, high fidelity methods for predicting the aeroacoustic behavior of aircraft components (and installations) are required since in the early stages of the development of innovative noise reduction technology test data is not available. The results are transferred to the second level, where radiation patterns of entire conventional and future aircraft concepts are assembled and noise emissions for single aircraft are computed. In the third level, large scale scenarios with many aircraft are considered to accurately predict the noise exposure for receivers on the ground. It is shown that reasonable predictions of the ground noise exposure level may be obtained. Furthermore, even though simplifications and omissions are introduced, it is shown that the method is capable of transferring all relevant physical aspects through the levels.
