Structural Design of an Adaptive Wing Trailing Edge for Enhanced Cruise Performance
'American Institute of Aeronautics and Astronautics (AIAA)', 2016Co-Authors: Pecora R., Amoroso F., Concilio A., Ciminello M.Abstract:Aircraft wings are usually optimized for a specific design point. However, since they operate in a wide variety of flight regimes, some of these have conflicting impacts on aircraft design process, as a single configuration may be efficient in one instance but perform poorly in others. In principle, stiff, hardly deformable aircraft structures preclude any adaptation to changing conditions. Alternatively, morphing wings could provide adaptive capabilities to maximize aircraft performance in any flight operation. Inside SARISTU, specific research activities were carried out on the technological development of an Adaptive Trailing Edge Device (ATED) implementing airfoil camber morphing for the maximization of the wing aerodynamic performance during cruise, with the ultimate goal to reduce fuel consumption. Wing shape is changed to compensate weight losses following fuel burning, to keep L/D ratio (or simply drag, D) to its optimal value. ATED camber adaptations are predicted to lead to significant benefits in fuel consumption, estimated from 3 to 5%, depending on a number of initial and boundary conditions. This paper is focused on the design process adopted for the definition and verification of ATED primary structure; fast and reliable elementary methods combined with rational design criteria and advanced FE analyses were adopted to assess the architectural concept and the embedded actuation mechanisms. Structural design was carried out in compliance with the very demanding requirements posed by the implementation of the device on Large Aeroplanes (EASA CS25 category)

Structural Design of an Adaptive Wing Trailing Edge for Large Aeroplanes
'Springer Science and Business Media LLC', 2015Co-Authors: Pecora R., Magnifico M., Amoroso F., Lecce L., Bellucci M., Concilio A., Ciminello M.Abstract:The structural design process of an adaptive wing trailing edge (ATED) was addressed in compliance with the demanding requirements posed by the implementation of the architecture on Large Aeroplanes. Fast and reliable elementary methods combined with rational design criteria were adopted in order to preliminarily define ATED box geometry, structural properties, and the general configuration of the embedded mechanisms enabling box morphing under the action of aerodynamic loads. Aeroelastic stability issues were duly taken in account in order to safely assess inertial and stiffness distributions of the primary structure as well as to provide requirements for the actuation system harmonics. Results and general guidelines coming from the preliminary design were then converted into detailed drawings of each box component. Implemented solutions were based on designer’s industrial experience and were mainly oriented to increase the structural robustness of the device, to minimize its manufacturing costs, and to simplify assembly and maintenance procedures. The static robustness of the executive layout was verified by means of linear and nonlinear stress analyses based on advanced FE models; dynamic aeroelastic behaviour of the stress-checked structure was finally investigated by means of rational analyses based on theoretical mode association
