Kurzfassung
A distributed pressure transducer array was installed on an Airbus model A320 airplane and measurements were performed under various cruise flight conditions. Turbulent boundary layer pressure fluctuations were recorded at several flight altitudes and velocities. The array was installed directly in front of the wing root by replacing three pax windows with aluminum dummy windows equipped with piezo-resistive pressure sensors. Evaluating the signals via a frequency-domain array processing technique provided information about local flow phenomena. Narrow-band convectional direction was extracted from the measurement data and decay of coherence was determined for the predominant flow direction. Two dimensional coherence of turbulent structures and wavenumber spectra were compared with the empirical models of Corcos and Efimtsov.
