This paper presents the design of a jet transport with high aspect ratio (AR 15.6) as well as an innovative laminar airfoil layout with natural laminar flow (NLF) realized by Crossflow Attenuated Natural Laminar Flow (CATNLF). The structural optimization considers CS-25 load cases and imposes aeroelastic constraints to ensure the performance of the laminar wing throughout the flight mission.
