Abstract

DLR’s concept for a natural laminar flow transonic transport aircraft with forward swept wings is presented. Giving an overview on the aircraft’s configurational layout first, the focus is on the multidisciplinary design of NLF wing and its aerodynamic performance. Results from high-fidelity coupled aero-structural simulations show that a significant extent of laminar flow is achievable. Torsional divergence of the wing is successfully suppressed by aeroelastic tailoring. The impact of elastic wing deformation on boundary layer stability and NLF performance is studied. Finally, results of the aircraft’s cruise performance and expected fuel savings are provided and compared to results from preliminary design.
