Advancements In UAV Wing Design: Aerodynamic Performance, Structural Integrity And Optimization Techniques

The aerodynamic performance and optimization of unmanned aerial vehicles (UAVs) have garnered significant research interest, driven by the need for enhanced efficiency, stability, and adaptability in various flight conditions. This paper reviews current research on UAV wing configurations, focusing on aerodynamic optimization, structural integrity, and computational fluid dynamics (CFD) analysis. Studies on innovative wing designs, such as blended-wing-body and fixed-wing configurations, demonstrate improvements in lift, drag, and maneuverability through precise airfoil selection and wing parameter optimization. Structural optimization, particularly the strength-to-weight ratio, is highlighted as essential for balancing aerodynamic performance with structural robustness. CFD analysis has proven valuable in evaluating the effects of wingtip devices and varying aerodynamic loads, enabling detailed assessments of airflow behavior, pressure distribution, and vortex formation. This review identifies key trends and gaps in the literature, emphasizing the potential of advanced simulation and optimization techniques to further enhance UAV performance, efficiency, and mission-specific adaptability
