A strong interest in highly-efficient, small-scale propeller configurations can be recognized, especially due to the currently growing number of and usage possibilities for unmanned aerial vehicles (UAVs). Although a variety of different propulsion concepts already exist on the market or are discussed in the literature, there is still a demand for a systematic investigation to compare such configurations, in particular, small-scale propellers with a fixed pitch, which are analyzed in this work.... »
This research (Project HyProp) was funded by the Bavarian Research Foundation (Bayerische Forschungsstiftung) under the grant number AZ-1277-17. The successful collaboration and support by the project partner Rolls-Royce Deutschland is highly acknowledged. Special thanks are addressed to ANSYS for providing the flow simulation software. Last but not least, the authors thank the company APC Propellers for providing the geometrical data of the analyzed propeller.
