Description du projet
Sur la voie de rails de volet imprimés en 3D pour les ailes d’avion
Les rails de volet contrôlent les volets situés sur le bord de fuite des ailes des avions. L’objectif du projet ADDIFLAP, financé par l’UE, consiste à mettre au point un nouveau concept pour le mécanisme d’un rail de volet combinant un système de soutien du rail de volet fabriqué par dépôt d’énergie directe et un système de transport fondé sur une structure coulissante. Le développement du procédé de dépôt d’énergie directe sera soutenu par des outils numériques afin de réduire les distorsions sur la structure finale du rail de volet et par un processus en ligne de suivi et de contrôle. Par rapport aux méthodes conventionnelles, cette technique de fabrication additive devrait réduire le gaspillage de matériaux de 60 %. Le système de transport coulissant devrait multiplier par deux les heures de vol du composant.
Objectif
ADDIFLAP project’s general aim is the development of a new concept of flap track system by combining a novel flap track support manufactured by Laser Wire Direct Energy Deposition (W-DED-LB) with a new design of carriage system based in sliding pad concept, made using a self-lubricant MMC coating.
Deployment of W-DED-LB process will be supported by numerical models to reduce the distortion effect on the final flap track structure and establish the manufacturing strategies for process manufacturing and by online process monitoring & control. Sliding pad design for the flap carriage system will be based on self-lubricant surfaces approach. ADDIFLAP involves the following objectives:
• Development of simulation models and optimized manufacturing strategies will reduce the effort in reducing the
distortion on the flap track support up to 50% regarding the trial-and-error approach. This will impact in the time to market, reducing even further the time from design to manufacturing.
• Flexibility (on design, enabling part consolidation…) provided by AM technologies (W-DED-LB) will enable to reduce the time to market into 20%.
• Reduction of 60% on material waste regarding conventional manufacturing is expected (Reduction of the BTF ratio).
• Reduction of 20-30% on component distortion will be achieved by combination of simulation, and optimization of WDED-LB process parameters and online monitoring & control developed in ADDIFLAP Project.
• The sliding carriage system will increase the component flying hours for a conventional Business Jet in a factor of two regarding conventional roller system.
The technology developed in ADDIFLAP will enable the design of a multifunctional flap which combines aileron and high lift functions in one flap body having direct impact on weight reduction.
