Electrification of air transportation pushes aircraft manufacturers such as BA to develop state-of-the-art tools and techniques to achieve certification more rapidly. One of these tools is numerical simulation, in particular real-time simulators coupled with hardware. This approach allows testing the integration of various components rapidly and at low cost, without having to develop full-scale mock-ups. One weak point of current simulation models is the power wires. In aircrafts, bundles of wires called "harnesses" follow complicated pathways, and the conducting parts of the fuselage used as current return path. This gives rise to complicated electromagnetic behavior that requires advanced modeling tools to produce wiring models. This problem can be solved by using several simulation tools that work fine individually, but which have never been coupled together. Starting from a cleaned CAD representation of harnesses routes plus conductors' specifications, one can use the S-PEEC method (Galileo EMT software) in order to generate frequency-dependent circuit parameters in the form of vector fitting functions, which in turn become inputs to Matlab/Simulink-based power circuit simulators (this passage represent a substantial R&D effort). Finally, in order to get closer to a real-time version of the model, an exploration of the possibilities to use hardware acceleration of the computations will be realized. The whole process will be automated through a computational workflow. Results will be extensively validated with experimental measurements performed on mock-ups of various level of complexity. The project will help all partners invovled to increase their ability to model complex electrical systems, and at the same time, that will increase their competitiveness on the market.

航空运输的电气化促使 BA 等飞机制造商开发最先进的工具和技术，以更快地获得认证。这些工具之一是数值模拟，特别是与硬件结合的实时模拟器。这种方法可以快速、低成本地测试各种组件的集成，而无需开发全尺寸的模型。当前仿真模型的一个弱点是电源线。在飞机上，称为“线束”的电线束遵循复杂的路径，机身的导电部分用作电流返回路径。这会产生复杂的电磁行为，需要先进的建模工具来生成接线模型。 这个问题可以通过使用多个单独工作但从未耦合在一起的仿真工具来解决。从线束路线和导体规格的清晰 CAD 表示开始，可以使用 S-PEEC 方法（Galileo EMT 软件）以矢量拟合函数的形式生成与频率相关的电路参数，这些参数反过来又成为基于 Matlab/Simulink 的电源电路模拟器（本文代表了大量的研发工作）。最后，为了更接近模型的实时版本，将探索使用计算的硬件加速的可能性。整个过程将通过计算工作流程实现自动化。结果将通过在不同复杂程度的模型上进行的实验测量得到广泛验证。 该项目将帮助所有相关合作伙伴提高复杂电气系统建模的能力，同时提高他们在市场上的竞争力。
