Optimal design and numerical analysis of a morphing flap structure

Over the next few years the aviation industry will face the challenge to develop a new generation of air vehicles characterised by high aerodynamic efficiency and low environmental impact. The technologies currently available, however, are inadequate to meet the demanding performance requirements and to comply with the stringent regulations in terms of polluting emissions. An innovative and very promising solution is offered by airframe morphing technologies. Morphing wing structures, internally actuated and able to change their shape smoothly to adapt to different loading conditions, would be able to achieve near-optimal lift and drag profiles throughout all the different phases of the flight. This would enhance the aircraft aerodynamic performance and contribute to a significant reduction of the fuel consumption, polluting emissions and noise. The present study has been conducted as part of the European Commission founded Seventh Framework Program called \Smart High Lift Device for the Next Generation Wing" (SADE). The aim of this research is the development of an effective design of a morphing ap with flexible trailing edge for a commercial aircraft wing. The investigation focused on morphing concepts which are suitable for large transport aircraft and which can be effectively developed and become operational within the next 20 years. For these reasons, the morphing was limited to the high lift devices of the wing, while the conventional wing box structure was retained. Cont/d.
