Description du projet
Le flambement au service des structures aérospatiales adaptatives
Le secteur aérospatial cherche à générer des gains d’efficacité significatifs en réduisant la consommation de carburant et les émissions tout en renforçant la sécurité. Les ailes déformables («morphing»)intelligentes et adaptatives sont conçues pour changer de forme sans accroc pendant le vol afin de réduire la traînée et d’améliorer l’efficacité. Le flambement est un phénomène structurel depuis longtemps jugé indésirable et qui est source d’instabilités, voire de défaillances. Le projet NABUCCO, financé par le CER, considère le flambement comme une opportunité de conception potentiellement révolutionnaire. Il exploitera les phénomènes de flambement dans la conception et la réalisation de structures composites adaptatives et d’ailes d’avion déformables. Des méthodes d’analyse, d’optimisation, de simulation et de test fortement améliorées tiendront compte de l’espace de conception étendu et garantiront la sécurité.
Objectif
The NABUCCO project aims to develop radically new concepts of adaptive and buckling-driven composite structures for next generation aircraft. In aeronautics, buckling is generally avoided because it causes stiffness reduction, large deformations, and can result in a catastrophic collapse. Instead, NABUCCO considers buckling no longer as a phenomenon to be avoided, but as a design opportunity to be explored for its ground-breaking potentialities. The idea is to use buckling drawbacks in a positive way, to conceive, design and realize adaptive structures and aircraft morphing wings. These new, lighter, flexible structures will be designed considering all the potentialities offered by composite materials, thanks also to novel manufacturing processes, and modifying the boundary conditions to govern when buckling occurs and to tune multiple non-traditional post-buckling stable configurations. These structures will be able to adapt their shape during different flight conditions, acting on two of the biggest levers for the future of clean aviation: reduced weight and increased efficiency. The concepts proposed in NABUCCO will require a step change for what concerns the design, analysis and optimization methodologies, since the design space will be significantly enlarged and the designer will need the ability to identify, manage and control the buckling phenomena. These solutions can be obtained by adopting an integrated design approach established on a multi-disciplinary thinking. A strongly coupled computational-experimental framework will be developed based on novel analytical formulations, artificial intelligence techniques for large multi-objective optimizations, high-fidelity simulation methodologies and advanced test techniques.
