Modern construction techniques in aerodynamic surface construction allow long runs of Natural Laminar Flow (NLF) along airfoils and fuselages provided that their shape has been properly designed. A numerical optimization iterative procedure for drag reduction by shape modification of mono- and multi-component airfoils and three-dimensional fuselages, has been developed. To this aim we propose a geometric parameterization of a general 3D body. Reduction of drag through an extension of laminar flow runs, for airfoils and 3D glider fuselages, is shown. A modular numerical code developed to perform shape optimization for drag reduction has proven to be efficient and reliable.

Abstract
Modern construction techniques in aerodynamic surface construction allow long runs of Natural Laminar Flow (NLF) along airfoils and fuselages provided that their shape has been properly designed.

To this aim we propose a geometric parameterization of a general 3D body. Reduction of drag through an extension of laminar flow runs, for airfoils and 3D glider fuselages, is shown.
