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.

本数据集汇聚了有限长度翼型在正弦波形和多孔端部产生的尖端涡流噪声测量数据。这些数据通过德国科特布斯布兰登堡工业大学（BTU）的专业航空声学测试设施，以及一套47通道平面麦克风阵列获取。在实验过程中，对超过2600个独特的测试案例进行了测量，包括翼型截面形状、尖端几何形状、攻角和雷诺数的变异。数据集包含经过Acoular处理的1/3倍频程尖端噪声频谱，Acoular是一个用于声束形成的Python模块。
