Experimental and numerical propeller dataset now openly available

Throughout the course of the project, several experimental and numerical studies have been conducted on multiple propeller designs. We are pleased to announce the open publication of these data so that any interested researcher can make good use of them. The dataset is available at Zenodo, under a Creative Commons-Attribution-Share Alike 4.0 license.

The propellers have been characterized experimentally at the wind tunnel “Francisco Payri” of CMT-UPV and also at the anechoic chamber of the same Institute. Some of them have also been simulated numerically, using different numerical approaches and commercial and open-source CFD codes.

The data includes at the moment of publication 9 propellers of various diameters and design geometries. These propellers have been studied under various operating conditions (including hover, advance flight, and edgewise flight), and in some cases, using a variety of materials and manufacturing techniques (wood, ABS plastic, resin…).

Measured or predicted thrust and torque data is included in the database and, when available, acoustic data has also been included, as well as geometric descriptions of the blade and the CAD models used in the numerical simulations.

The data collected in the repository is currently being used to verify different computational methods, as well as to design strategies to reduce noise pollution. By publishing this data, we hope it will allow other researchers to benefit from it and continue to advance this area of research. As we continue to analyze more propellers, the repository will be continuously updated.
