Dataset corresponding to the publication : Serration Manufacturing Effects on Propeller Trailing Edge Noise Mechanisms, Santamaria et al., JSV, 2026.

Rotors with trailing edge serrations as presented in Santamaria, Belliot, Sanjosé, Gojon, and Moreau. Serration Manufacturing Effects on Propeller Trailing Edge Noise Mechanisms. Journal of Sound and Vibrations, 2026. Thrust and torque coefficients, Figure of Merit, as well as acoustic autopower signals are provided. CAD files of the serrated and clean rotors, as well as example Matlab code to post-process acoustic results are also given. For aerodynamic results, the thrust and torque coefficients are given as a function of RPM. Fluid density is taken as 1.18kg/m3. For acoustic results, the autopower (Pa2) is given as a function of the frequency (Hz). Autopowers are obtained from fluctuating pressure time signals (16s) by computing the fast Fourier transform (FFT) with a Hanning window applied on 100 segments, using a 50% overlap and a magnitude correction factor, which leads to a frequency resolution of 3.125 Hz. Structure of the acoustic data For each rotation speed, data for 13 microphones located 1.62m away from the rotor axis and at different angles (every 10 degrees) from the rotor plane are provided. Microphone 1 corresponds to +60 degrees (as compared with the rotor plane, where + indicates that it is located in the direction opposite of the flow, as visible in Figure 5 of the corresponding journal paper) Microphone 2 corresponds to +50 degrees ... Microphone 7 corresponds to 0 degrees (the rotor disk plane) ... Microphone 13 corresponds to -60 degrees
