Description of this data

This dataset consists of measurements of tip vortex formation noise produced by finite-length airfoils with flat and rounded tips. These data were obtained using the specialist aeroacoustic test facilities at the Brandenburg University of Technology (BTU) in Cottbus, Germany and a 47-channel planar microphone array. Over 1200 unique test cases with variations in airfoil profile shape, tip geometry, angle of attack and Reynolds number were measured during the experimental campaign. The dataset contains one-third-octave band tip noise spectra that have been processed using Acoular, a Python module for acoustic beamforming.

Steps to reproduce

Acoustic measurements were performed in a quasi-anechoic open jet wind tunnel at the Brandenburg University of Technology. The airfoils used in this study have NACAxx12 profile with 0, 2, 4 and 6% camber at 40% chord and NACA00xx profile with thickness of 12, 15 and 18%. Acoustic data were obtained using a planar microphone array containing 47 microphones. Acoustic measurements were taken at Reynolds numbers based on chord of 2.5e4 to 2.25e5 and geometric angles of attack between -10 and 20 degrees.
