Low Reynolds Number Wing Design for Unmanned Aerial Vehicle: A Case Study

Abstract

With the widespread utilization of Unmanned Aerial Vehicles (UAVs) in many fields, it is essential to identify the parameters governing their design process. By taking the wing as a showcase, this study intends to guide through the design process of the wing, elaborate on some important definitions, and show how different parts of an aircraft affect each other. The current case study is limited to low Reynolds number (200,000: 500,000) wing design for unmanned aerial vehicle. The final wing was designed to be rectangular, a high wing with a span of 2 m, a chord of 0.4 m, and a corresponding aspect ratio of 5 with a total take-off weight of 10 kg. While the cruising speed and stall speeds were 14 and 11 m/s respectively.
