Descripción del proyecto
Materializar el potencial del pandeo en pos de unas estructuras aeroespaciales adaptables
El sector aeroespacial aspira a lograr un aumento significativo de su eficiencia al reducir sus emisiones y su consumo de combustible y mejorar su seguridad. Las alas inteligentes y adaptables que cambian de forma sin problemas durante el vuelo minimizan la resistencia y mejoran la eficiencia. Un fenómeno estructural que durante mucho tiempo se ha considerado indeseable es el pandeo, que provoca inestabilidad e incluso fallos. El equipo del proyecto NABUCCO, financiado por el Consejo Europeo de Investigación, considera el pandeo como una oportunidad de diseño con una capacidad potencialmente pionera. Aprovechará los fenómenos de pandeo en el diseño y la realización de estructuras adaptativas de materiales compuestos y alas de aeronaves que cambian de forma. Las metodologías de análisis, optimización, simulación y prueba, significativamente mejoradas, tendrán en cuenta la ampliación del espacio de diseño y garantizarán la seguridad.
Objetivo
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.
