We continue our study on the aerodynamic performance of a Wing-Embedded Propeller (WEP) system by considering the effect of propeller installation location along the span and its overall size on the entire system. Six semi-span AR 2 wings with different spanwise opening locations and opening diameter-to-wing-chord ratios were investigated numerically using FlightStream® and experimentally in the University of Dayton Low-Speed Wind Tunnel without the installation of the propeller. The propeller is then installed and tested experimentally. Without the propeller, the wing with the opening closer to the wingtip experiences the least detriment to overall aerodynamic performance. Integrating the propeller into the WEP system and positioning it at the wing's mid-span, results in better overall performance. Increasing the propeller size has a more pronounced effect on the WEP system, increasing both lift and forward thrust generation. The linear superposition method is suitable for estimating the WEP system lift performance at a higher propeller incidence angle. However, it significantly underestimates the drag produced by the WEP system. This trend is consistent across all wing locations and propeller sizes tested in this study. © 2024 by Emma Schutter, Caiden Guzman, Jielong Cai, Sidaard Gunasekaran.
