Description du projet
La recherche décolle pour révolutionner les réparations aérospatiales
Le secteur aérospatial est confronté à d’importants défis en matière de réparation et de remanufacturage de composants essentiels tels que les pales de turbines et les trains d’atterrissage, des procédures qui peuvent s’avérer coûteuses et chronophages. Le processus de fabrication additive (FA) par dépôt sous énergie concentrée (DED) offre une solution innovante. Toutefois, il est nécessaire de comprendre la précision et les limites des processus de dépôt ainsi que la caractérisation effective de la géométrie des défauts. Le projet AMOS, financé par l’UE, entend mener des recherches fondamentales sur les processus de FA par DED, établir des études comparatives et développer des méthodes pluridisciplinaires d’optimisation de la conception afin de réduire, à terme, les faiblesses des composants aérospatiaux au stade de la conception. Les résultats de ce projet seront utiles aux fabricants d’équipements d’origine ainsi qu’aux PME dans leur choix des stratégies de réparation et de remanufacturage appropriées.
Objectif
This research project focuses on several key Direct Energy Deposition (DED) Additive Manufacturing (AM) processes that have great potential to be used as cost-effective and efficient repairing and re-manufacturing processes for aerospace components such as turbine blades and landing gears. This project aims to conduct fundamental research to understand the material integrity through chosen DED AM processes, the accuracy and limitations of these deposition processes, effective defect geometry mapping and generation methods, and automated and hybrid DED and post-deposition machining strategies. This project intends to connect repair and re-manufacturing strategies with design through accurate DED process simulation and novel multi-disciplinary design optimisation (MDO) methods to ultimately reduce the weakness of aerospace component at design stage and prolong their the lifecycles. Both powder-based and wire-based DED systems will be investigated to establish an across-the-board comparative study. The data collected through this comprehensive comparative study will be extremely valuable for the OEMs of this project (i.e. GKN, PWC, and HDI) to understand the pros and cons of these DED systems and will help them to select suitable repair and re-manufacturing strategies. The tests conducted in this research are also extremely beneficial for the SMEs in this project (i.e. Liburdi, AV&R, DPS) to validate their existing repairing systems and techniques.
