Analysis Report of Large UAV Wing Aerodynamic Characteristics

Currently, drones are widely used as a powerful aircraft. Drones have reliable maneuverability, wide flight range, and powerful and stable data collection capabilities, making them increasingly widely used in military, industrial surveying, safety monitoring, emergency response, and other fields. This article takes a large unmanned wing as the research object and conducts aerodynamic analysis based on computational fluid dynamics to determine the optimization results under different usage conditions. Two turbulence calculation models, <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$k-\omega$</tex> SST and Spalart Allmaras, were selected based on the wing prototype in the <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$A, B, G$</tex>, and <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$W$</tex> airspace to analyze one large UAV wing's aerodynamic characteristics, including lift characteristics and resistance characteristics. Performance parameters such as velocity and pressure cloud, lift coefficient and drag coefficient distribution of the wing at different angles of attack and Mach number were obtained.
