Descripción del proyecto
Puertas de carga de aeronaves ecológicas y de alta calidad
Los costes de fabricación desorbitados y la contaminación ambiental son los dos principales retos a los que se enfrentan las puertas de carga metálicas de las aeronaves. El equipo del proyecto MISSP, financiado con fondos europeos, pretende resolver estos problemas desarrollando estructuras más baratas y ecológicas para todos los paneles de revestimiento rígido. Aprovechando los materiales avanzados, las técnicas de fabricación y los conceptos de diseño, en MISSP se abordarán los retos más acuciantes de la industria. Mediante la sustitución del fresado químico por el mecanizado mecánico plano y la integración de componentes para reducir los procesos de montaje, en este proyecto se ofrecerá un cambio de paradigma en la fabricación. Incluyendo tres paquetes de trabajo técnico fundamentales, seguidos de un exhaustivo análisis de costes y rendimiento, el equipo del proyecto MISSP promete una solución transformadora. El proyecto allanará el camino para unas puertas de carga de aeronaves de alta calidad y respetuosas con el medioambiente que revolucionarán el sector.
Objetivo
MISSP (Manufacturing of Integral Stiffened Skin Panels) project aims at proposing new manufacturing concepts for metallic aircraft cargo doors. The main objective of this project will be to develop cheaper and greener structures as an alternative to CFRP doors but also applicable for any stiffened skin panel structure. This will be made possible by the use of advanced materials, manufacturing techniques and design concepts. Expensive and polluting chemical milling operations shall be replaced by flat mechanical machining, while multi-parts riveted components shall be replaced by more integrated structures reducing the number of parts and the time-consuming mechanical riveting assembly processes
The project will be divided into 3 main technical work packages, followed by a cost and performance analysis. The first work package shall focus on the manufacturing of the external door skin with the aim of replacing the chemically milled pockets by mechanically machined ones. Both stretch-forming on tailored tool blocks and high energy hydroforming alternative will be investigated. In the second work package, stringers shall be integrated to the Al-Mg-Sc 5028 skin by flat welding (FSW or LBW) followed by creep forming. Finally, the third package shall be dedicated to the manufacturing of an integral structure, drastically limiting the number of assembly operations. To this aim, an innovative solution is proposed: a plate shall be deformed by high energy hydroforming and subsequently machined into the final cargo door integral structure.
To support the advanced manufacturing technologies proposed in this challenging project, use shall be made of numerical modelling that will help designing appropriated tools and optimizing process parameters to achieve high quality demonstrators that shall be delivered to the topic manager.
