Abstract: Birds' graceful and effective flying abilities have captured human imagination for millennia, serving as a constant source of inspiration for the aviation industry. This essay investigates how avian flight has influenced modern aviation, emphasizing important elements such wing shape, wing flexibility, flapping flight, and aerodynamics. It explores aviation's biomimetic uses, such as wing loading and shape, morphing wing technology, and flow control systems modeled after avian flight. The research also looks at improvements in safety and effectiveness brought about by avian flight mechanics, such as effective path planning and navigation, avoidance and detection systems, and mitigation measures for bird strikes. It covers the prospects for biologically inspired aircraft design, AI integration, and sustainability in contemporary aviation.
