Abstract

Modem tectrniques 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.
