Kurzfassung
The study presents recent results of DLR’s research on landing and take-off noise generated by novel supersonic transport aircraft. These activities have been started in 2020 in a cooperation with EASA. The focus was on single event noise due to ongoing discussions about noise certification of novel SST aircraft. First findings have been published with the focus on certification noise of business jets and the application of different rule proposals as suggested by regulation authorities. The new results presented in this report are based on these initial studies but now updated and additional simulation models are applied, e.g., application of an acoustic engine liner. One goal of this report is a status update of the simulation capabilities available within DLR. The updated simulation process is then applied to investigate two available SST business jets as introduced in previous publications. At first, operational noise reduction measures for the take-off are assessed as initially proposed by NASA. No modification to the approach procedures is considered for now. Based on this assessment, the vehicles are then further assessed along their most promising flight trajectory. Furthermore, the transition from single event to a scenario noise assessment based on a Doc9911 conform method is realized and presented. Both concept aircraft are then subject to a newly realized method to generate input data as required for the scenario assessment with Doc9911 based tools, e.g., the tool Impact. A first assessment of such a scenario implementation for the two concept aircraft is presented. Ultimately, the paper demonstrates the status quo and an application of the multi-level SST simulation process at DLR, i.e., combining the individual component level, the total aicraft level, and the scenario level.
