“…Additionally, factors such as structural design complexity and trim considerations should be taken into account, favoring airfoils with greater thickness and lower moment coefficients [32]. Preliminary screening of airfoils in the Profili airfoil database is conducted within the thickness range of 10% to 14% and camber range of 3% to 8% under a Reynolds number of 300,000 [33]. Among the selected candidates, including MH115, SD-7032-099-88, E214, Eppler67, and FX63-110, a detailed comparison is carried out regarding polar curves, lift-to-drag ratios, drag coefficients, and moment coefficients.…”

The development of solar-powered unmanned aerial vehicles (UAVs) primarily focuses on enhancing the efficiency of the propulsion system to minimize energy consumption during the conversion of valuable solar energy. However, due to the unique nature of UAV propulsion systems, there is limited cross-reference ability among existing solar-powered UAV systems. This paper proposes an integrated design approach for the propulsion system and UAV structure. Based on this approach, an overall design is conducted for the solar-powered UAV, including initial design goals and performance parameters. Aerodynamic layout design and performance estimation are carried out, and a prototype is fabricated and assembled for flight testing validation. The results demonstrate the significant importance of this approach in improving the efficiency of the solar-powered UAV propulsion system.
