CFD simulation of the Impact of Eagle Bioinspired Wing Slots for Reducing Induced Drag and Enhancing Flight Efficiency in UAVs
Year: 2025
Type: article
Abstract: This research examines the aerodynamic performance of three UAV wing configurations base wing, Model A with cambered wingslots, and Model B with symmetrical wingslots at low Reynolds numbers. Using CFD simulations in ANSYS FLUENT, key parameters such as lift coefficient, drag coefficient, induced drag, and lift-to-drag ratio were analysed across angles of attack from 0° to 15° and flight velocities of 8 m/s, 10 m/s, and 12 m/s. Results reveal that wing slots enhance aerodynamic efficiency by 12.5% at low angles of attack. Model A with cambered wingslots excels in pre-stall lift generation, while Model B with symmetrical wingslots achieves lower drag at lower angles. Both configu-rations significantly reduce induced drag by up to 29% during cruise conditions, highlighting their effectiveness in im-proving UAV performance.
