Description du projet
Portes d’avion de transport de haute qualité et respectueuses de l’environnement
Les coûts de fabrication exorbitants et la pollution de l’environnement sont les deux principaux défis auxquels sont confrontées les portes métalliques des avions de transport. Le projet MISSP, financé par l’UE, vise à résoudre ces problèmes en développant des structures moins chères et plus écologiques pour tous les panneaux raidis. En exploitant des matériaux, des techniques de fabrication et des concepts de conception avancés, MISSP s’attaquera de front aux défis les plus pressants de l’industrie. En remplaçant le fraisage chimique par l’usinage mécanique à plat et en intégrant des composants permettant de réduire les processus d’assemblage, ce projet apportera un changement de paradigme à la fabrication. Comprenant trois volets techniques essentiels, suivis d’une analyse complète des coûts et des performances, le programme MISSP promet une solution transformatrice. Le projet ouvrira la voie à des portes d’avion de transport de haute qualité et respectueuses de l’environnement qui révolutionneront le secteur.
Objectif
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.
