| dc.description.abstract | The data collection consists of measurements of tip vortex formation noise produced by a finite length airfoil with porous and sinusoidal tip geometries. These data were obtained using the specialist aeroacoustic test facilities at the Brandenburg University of Technology in Cottbus, Germany. Over 2600 unique test cases with variations in airfoil tip geometry, angle of attack and Reynolds number were measured during the experimental campaign. The dataset contains raw microphone array data and data processed using Acoular, a Python module that produces acoustic maps of sound source distributions and one-third octave band tip noise spectra. | en_US |

| dcterms.accrualMethod | 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 chord length of 70 mm, aspect ratio of 2, NACA0012 and NACA6412 profile and an interchangeable tip. For the NACA0012 airfoil, 11 sinusoidal tips and 8 porous tips were tested. The sinusoidal tips have amplitude of 3 to 10 mm and a wavelength of 7 to 23.3 mm. For the porous tips, porosities between 5.14 and 50.3% were achieved by varying the size and location of the pores on the tip surface. For the NACA6412 airfoil, 6 selected sinusoidal tips and 3 selected porous tips were tested. 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. | en_US |
