This test, led by the DLR Braunschweig, is dedicated to high lift noise and is related to the German national Lufo project FTEG as well as the EU-project OPENAIR.
For the first time, highly valuable flow and acoustic data is expected, which will not be biased by unrealistic Reynolds number effects and unavoidable artefacts due to small scale testing.
