Aerodynamic Shape Optimization of an Adaptive Morphing Trailing Edge Wing [PDF]
15th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2014 Adaptive morphing trailing-edge wings have the potential to reduce the fuel burn of transport aircraft. However, to take full advantage of this technology and to quantify its benefits, design studies are required. To address this need, the aerodynamic performance benefits of a morphing trailing-edge wing are quantified using aerodynamic design ...
