Dataset on tip vortex formation noise produced by wall-mounted finite airfoils with sinusoidal and porous airfoil tip geometries

This dataset consists of measurements of tip vortex formation noise produced by finite length airfoils with sinusoidal and porous 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 2600 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.
