In the LuFo VI-2 project DIMENSION, the goal is to achieve value enhancement in the field of aircraft cargo and passenger doors through innovative solutions addressing various technical, operational, and systemic aspects. The project builds upon a previous LuFo initiative, FUDOS, and additionally aims to further develop the already researched technological innovations of fully electric passenger doors, raising them to a higher Technology Readiness Level (TRL).
Overall, a modular system framework for the accelerated and cost-efficient development of new aircraft doors is to be established, taking significant steps towards model-based systems engineering and multidisciplinary design optimization. In pursuit of this goal, work will be carried out on many subcomponents related to control systems, structure, and validation concepts. From a structural perspective, the Institute of Aircraft Design (IFB) will explore novel door architectures based on thermoplastic carbon-fiber composite construction. Within two work packages, innovative infusion and joining processes using thermoplastic matrix systems will be investigated, along with process simulations of thermally joined carbon-fiber structures, focusing particularly on thermal distortion effects. Building on these results, new door architectures will be identified from a structural standpoint.
The DIMENSION project is led by Airbus Operations GmbH (AiO) and carried out in collaboration with the project partners Airbus Helicopters (AHD), CirComp (Albint), the German Aerospace Center (DLR), the Fraunhofer Society (IISB, ICT & LBF), Micro-Epsilon, and Wittenstein as an associated project partner.
