This project supports the digital transformation of aircraft design by developing new multi-disciplinary and multi-fidelity simulation tools that will enable novel aircraft architectures with improved aerodynamics and reduced noise emissions. This project addresses more specifically the design issues of electric Vertical Take-Off and Landing aircraft developed for Urban Air Mobility, but the innovative design/optimization framework that are proposed in this project are equally applicable to other novel aircraft architectures, such as those based on Distributed Electric Propulsion, Boundary Layer Ingestion, or open rotors. One common issue for most novel aircraft concepts is indeed the complexity of the aerodynamic and acoustic interactions between the lift-thrust systems and the airframe. eVTOLUTION is designed as a low-to-mid-TRL enabler project meant to develop the knowledge, data, tools, and methods that are necessary to understand, model, and optimize aerodynamic and aeroacoustic installation effects. The main objective of the project isto implement and demonstrate a novel design and optimization framework, built upon three pillars: (i) exploit the strengths of low-, mid-, and high-fidelity simulation methods at each phase of the design; (ii) accelerate the optimizations while preserving robustness thanks to data-driven surrogate models combined with physical models; and (iii) further consolidate the accuracy and robustness of the design and optimization using advanced experimental/numerical cross-validation and training methodologies. The realization of these objectives will be achieved through design exercises, defined by the consortium under the guidance of its aircraft manufacturers. The analysis of the design exercises will permit quantifying the gains achieved in terms of design cycle time, prediction accuracy, optimization robustness, the efficiency of the noise mitigation technologies, and eventually the acceleration of the certification process.

该项目通过开发新的多学科和多保真模拟工具来支持飞机设计的数字化转换，该工具将使新型飞机体系结构具有改进的空气动力学和减少的噪声排放。该项目更具体地解决了用于城市空气移动性的电力垂直起飞和着陆飞机的设计问题，但是该项目中提出的创新设计/优化框架同样适用于其他新型飞机架构，例如基于分布式电动推进，边界层，边界层摄入或开放旋翼的飞机建筑。对于大多数新型飞机概念而言，一个常见的问题确实是升降机系统与机身之间空气动力和声学相互作用的复杂性。 Evtolution被设计为一个低到中的TRL启用器项目，旨在开发了解，建模和优化空气动力学和空气声学安装效果所必需的知识，数据，工具和方法。该项目的主要目标是实施并展示了一个新颖的设计和优化框架，该框架建立在三个支柱上：（i）在设计的每个阶段都利用低，中，中高的仿真方法的优势； （ii）通过数据驱动的替代模型与物理模型相结合，在保持鲁棒性的同时加速了优化； （iii）使用先进的实验/数值交叉验证和训练方法进一步巩固了设计和优化的准确性和鲁棒性。这些目标的实现将通过在飞机制造商的指导下定义的设计练习来实现。对设计练习的分析将允许根据设计周期时间，预测准确性，优化鲁棒性，降解技术的效率以及最终加速认证过程来量化所取得的收益。
