Dataset on tip vortex formation noise produced by wall-mounted finite airfoils with flat and rounded tip geometries

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.

本数据集汇聚了由有限长翼型产生的尖端涡旋形成噪声的测量值，其中翼型尖端呈扁平或圆形。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个47通道平面麦克风阵列获取。在实验过程中，对超过1200个独特的测试案例进行了测量，这些案例在翼型截面形状、尖端几何形状、攻角和雷诺数等方面存在变化。数据集包含经Acoular处理的三分之一倍频程尖端噪声频谱，Acoular是一款用于声束成形的Python模块。
