Acoustic data of a small-scale rotor at four advance ratios -- including hover

Data and the experimental acquisition procedure are described in the following publication:Baars, W.J., Ragni, D. (2023) Low-frequency intensity modulation of high-frequency rotor noise. AIAA-2023-3215.<br>Data comprise timeseries of the acoustic pressure, acquired at a grid of positions spanning the near- and far-fields of a small-scale rotor. Various operating conditions of the rotor are considered: one hovering condition (zero advance ratio), and three forward flight conditions (non-zero advance ratios). These data allow for studying the noise imprint of small-scale rotors.<br>

本数据集的数据与实验采集流程详见下述文献：Baars, W.J.、Ragni, D.（2023）《高频旋翼噪声的低频强度调制》，AIAA-2023-3215。
数据集包含小型旋翼近场与远场范围内多位置网格采集得到的声压时间序列。
本数据集涵盖小型旋翼的多种运行工况：1种悬停工况（前进比（advance ratio）为0）与3种前飞工况（前进比非0），该数据集可用于开展小型旋翼的噪声特征研究。
