Kurzfassung
I will present the microphone array measurement technique which was advanced at the DLR Göttingen for the use in cryogenic and/or pressurized wind tunnels. This extends the range for acoustic measurements on scaled aircraft models in start and landing configuration up to real-flight Reynolds numbers. This abstract describes the measurements carried out in the European Transonic Wind Tunnel (ETW) and presents the results. I will also give additional examples for measurements performed in a cryogenic wind tunnel and give an insight in the comparability of microphone array measurements. In the example chosen, results obtained from the same model but different wind tunnels are being compared.
