Abstract
Within a parametric study on brush-type trailing edge extensions the noise reduction potential of several design concepts was determined. The obtained data base represents the first phase of an ongoing project with the long-term objective to develop scaling laws for a future application of such devices as add-on solutions for today's aircraft components. The experiments comprised both acoustic and aerodynamic measurements on a zero-lift generic plate model (Re = 2.1 to 7.9 x 10 Million) in DLR's open jet Aeroacoustic Wind Tunnel Braunschweig, AWB. Noise data were taken by means of a directional microphone system.
