Kurzfassung
Coherence lengths of the turbulent boundary layer pressure fluctuations were measured in flight on the A320 "ATRA" test carrier. A 3-window array was used in order to characterize the pressure fluctuations. The problem of an unknown flow direction was approached by utilizing the two-dimensional sensor distribution and a 2D fitting method rather than a 1D fitting method. Using the analysis, both, lateral coherence length, longitudinal coherence length, and local flow angle were measured. The coherence lengths were compared to model predictions and the importance of taking the flow angle into account was confirmed.
