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.

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.
