ABSTRACT: Aircraft aerodynamics has progressed from traditional fixed-geometry wing optimization to adaptive and morphing systems intended for multi-regime performance. Early advances in lift theory, boundary layer analysis, finite-wing effects, and compressibility laid the groundwork for systematic aerodynamic design. The computational age saw the introduction of supercritical airfoils, CFD, and multidisciplinary optimization, which improved transonic and high-speed flight efficiency. However, conventional wings are still confined by static geometry designed for certain operating situations. Bio-inspired morphing technologies allow for continuous span, camber, and twist change, which expands the aerodynamic performance envelope while lowering drag and structural loads. Active flow control methods improve boundary layer management. This paper summarizes underlying theory, computational breakthroughs, morphing structures, and intelligent control systems, highlighting their importance in promoting sustainable, high-efficiency aircraft.
