Description of this data

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.

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 dataset are NACA0012 and NACA6412 (6 % camber at 40 % chord) airfoil profiles with sinusoidal and porous airfoil tip geometries. 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.
