LERCat Data: Aeroacoustic Wind Tunnel Measurements

Aeroacoustic dataset from the Poul la Cour Tunnel measures as part of the LERCat project.Acoustic far field noise captured by a microphone array positioned 2.3m from the trailing edge with setup decribed in Related Materials. Additional acoustic data from surface microphones captured by 4 GRAS 48LX-1 UTP microphones mounted on the airfoil surface at four chordwise positions.Each file in this collection consists of rows of 1/12th octave band spectra associated to a measurement via the *meas_id*. The *meas_series_id* can be used to link information from the *LERCat dataset overview.csv*.TE_noise.csv: Trailing edge noise obtained from acoustic images using a microphone array.surf_mic_TE_H.csv: Surface microphone 1/12th octave spectrum. Microphone positioned 0.9c at z=722mm above floor.surf_mic_TE_L.csv: Surface microphone 1/12th octave spectrum. Microphone positioned 0.9c at z=692mm above floor.surf_mic_Mid.csv: Surface microphone 1/12th octave spectrum. Microphone positioned 0.5c at z=935mm above floor.surf_mic_LE.csv: Surface microphone 1/12th octave spectrum. Microphone positioned 0.17z at z=450mm above floor.
