Numerical Investigations of low Reynolds number Aerodynamics of Bio-Inspired 3D wings

The silent flight of owls is a result of unique physical features and adaptations, which has been studied by both biologists and engineers to enhance the design of unmanned aerial vehicles (UAVs). This study investigates the flight mechanics and aerodynamics of UAVs with a wing of aspect ratio of four and varying swept angles and taper ratios, using bio-inspired wing. Different configurations are tested by varying the swept angle and taper ratio to optimize design and ensure peak performance under different conditions and angles of attack. The behavior of the wings in various flying scenarios is used to research the aerodynamics and mechanics of flight. Although simulating folding bio-inspired wings is a thrilling field with revolutionary potential for UAV design, wingtips are identified as a source of three-dimensional flow that slightly lowers pressure towards the wingtip regions. This work enhances our understanding of aerodynamics and mechanics, leading to improved UAV design.
