Adaptive Tools for Electromagnetics and Materials Modelling to Bridge the Gap between Design and Manufacturing (AOTOMAT)

为了应对地平线2020 JTP文件“清洁天空2”（CS2）中提出的挑战，整个行业都期望采用全新的方法来进行飞机设计，空气动力学以及新功能和结构能力的集成，这些功能和结构能力共同提供显着的重量和燃料节省。通信系统的当前设计基于非共形解决方案和/或使用机械可操纵抛物面碟形天线（笨重）或相控阵列（昂贵）的机械可操纵天线系统，两者都覆盖有过多的天线罩。这些解决方案是突出的，增加气动阻力，燃油消耗，能见度，并降低操纵品质。为了实现这一步的变化，需要无缝嵌入天线和通信系统，使它们成为飞机机身的一部分，使用新型先进材料制成。这个概念提出了一个高度创新但具有挑战性的目标，因为解决方案还必须以合理的成本制造，同时满足结构和系统功能。电磁挑战是提出一种共形嵌入式通信系统设计，该设计不会降低性能，并且允许在存在结构材料的情况下在单个平台上的多个天线之间的互操作性。此外，必须考虑新功能对严格的机械和安全性能的影响，并且必须保持基于MRO的维修和维护的可能性。因此，需要一种自适应设计方法，以优化（i）电磁性能，（ii）基于实际负载和非线性振动的空气动力学性能，以及（iii）可制造性，特别是利用最新的3D添加剂方法嵌入功能材料。我们的目标是开发一种新的计算工具集，该工具集将基于电磁学，原子尺度材料和数据驱动建模的最新科学进展，无论是在功能结构维度还是在多尺度几何复杂性上。这一部署将提供可靠的设计方法，通过在现实的时间范围内提供结果，可以最大限度地减少原型阶段的成本，并将导致与飞机相关的最佳工程设计，最好的情况下是临时的，最坏的情况下是启发式的。

There is an industry-wide expectation that in order to meet the challenges laid out in the Horizon 2020 JTP document Clean Sky 2 (CS2), radically novel approaches are needed for the aircraft design, aerodynamics and the integration of novel functional and structural capabilities that together provide significant to savings weight and fuel. Current designs of communication system are based on non-conformal solutions and/or mechanically steerable antenna systems using mechanically steerable parabolic dishes (bulky) or phased arrays (expensive), both covered with excessive radomes. These solutions are protuberant, increasing aerodynamic drag, fuel consumption, visibility, and degrading handling qualities.To enable this step change, seamlessly embedded antennas and communication systems are needed so that they become part of the aircraft fuselage, which are constructed using novel advanced materials. This concept presents a highly innovative but challenging objective since solutions must also be manufacturable at sensible cost while meeting structural and system functionalities. The electromagnetic challenge is to come up with a conformal embedded communication system design that does not degrade performance, and allows interoperability between multiple antennas on a single platform in the presence of structural materials. In addition, the effects of new functionalities on strict mechanical and safety performance must be considered, and MRO-based repair and maintenance must remain possible.An adaptive approach to design is therefore required to optimize across (i) electromagnetic performance, (ii) aerodynamic performance based on realistic loads and non-linear vibrations and (iii) manufacturability, particularly drawing on latest 3D additive approaches to embedded functional materials. We aim to develop a novel computational tool-set that will be based on recent scientific advances in electromagnetics, atomistic-scale material and data-driven modelling both at the functional-structural dimensions and over the multi-scale geometric complexity. This deployment will provide robust design methodologies that can minimize the cost during the prototyping stage by providing results in a realistic time frame and will lead to optimal engineering designs in relation to aircraft that are ad hoc at best and heuristic at worst.
