The conventional method of optimizing the aerodynamic performance an airfoil heavily depends on confines design space. variables create a non-normalized space that is fragmented into several different clusters airfoils. An approach data-driven and deforms airfoils over Grassmannian submanifold utilized in work being presented here. affine deformation, which includes camber thickness, can be uncoupled from currently use, operations are performed shape made smooth enough to prevent unreasonable shapes produced. CST also part current study so comparison between two. A new describe geometries was generated using dataset contained 7007 These two methods used parameterize subsonic (NACA0012) transonic (RAE2822) airfoils, cuts number twelve six, resulting reduction overall complexity. findings demonstrate maintains high degree consistency regardless flow conditions.
