Paragraph starter
The aerodynamic performance of an airfoil is fundamentally linked to its geometric characteristics, including its cross-sectional profile and thickness. Research by Seeni (2022) suggests that applying principles of classical mechanics to airfoil design reveals how 'contraction' and 'expansion' within the geometry can be leveraged for lift generation, and that airfoil thickness is a critical factor in optimizing the balance between lift and drag.
