In the quest for a sustainable aviation many new innovations are taking place while other old technologies are being revised. Such is the case of distributed electric propulsion. For this type of technology (the same used as on the NASA N3-X (Felder JL, NASA N3-X with turboelectric distributed propulsion (2014, November). https://ntrs.nasa.gov/archive. Accessed 10 Jul 2020) for instance), ducted propellers are used to increase overall efficiency and aerodynamic performance of the aircraft. It is no doubt that electric distributed propulsion has some advantages (Kim HD, 27th International Congress of the Aeronautical Sciences at NASA Glenn Research Center, Distributed Propulsion Vehicles, 2010; Kim HD, Felder JL, Brown GV, Turboelectric distributed propulsion in a hybrid wing body aircraft, 2011) over classic propulsion configurations such as for instance improved maneuverability, control surfaces area reduction and hence weight reduction, boundary layer ingestion (Friedrichs J, Budziszewski N, Energies 11, Modelling of a boundary layer ingesting propulsor, 2018) and more. In this paper it is the effect of the duct over the propeller efficiency which will be quantified. To do so, a test bench equipped with high resolution sensors has been built to effectively test, measure and analyze electric drone propellers in different configurations. This has allowed to quantify the increase in performance the installation of a simple duct can bring. A further study should be conducted to quantify the induced drag due to the duct to compare positive and negative effects.
