FALCON

2017年，航空直接排放占欧盟二氧化碳排放总量的3.8%，占运输排放的13.9%，是仅次于道路运输的第二大温室气体排放源。此外，日益增长的空中交通流量意味着许多欧盟公民仍然暴露在高噪音水平下。因此，需要加强研究和创新活动，以减少所有航空影响和排放(二氧化碳和非二氧化碳、噪音、制造业)，以便欧盟实现到2050年实现温室气体净零排放的政策目标。减少二氧化碳排放的主要手段之一是减轻机身结构重量。作为答案，猎鹰的雄心是增强欧洲工业飞机部门的设计能力，专注于流体结构相互作用(FSI)现象，以改善飞机的空气动力学性能(非稳定载荷)。具体地说，猎鹰的目标是为航空领域的FSI开发高性能、可预测和多学科的工具，以便通过多保真优化来降低气动声学和气动弹性不稳定性。这也将有利于柔性和移动式机身结构在暴露于低速和高速流体流动时产生的特定噪声排放。为了实现其雄心勃勃的目标，猎鹰组建了一个独特的跨学科环境，由15个公共和私人机构及其附属实体(从著名的研究机构到中小企业和飞机高端供应商和集成商)组成，涵盖所有必要的科学和专有技术专业知识。在三个行业测试案例和与清洁航空等关键欧洲合作伙伴的紧密联系的基础上，猎鹰勾勒出了一个高影响/低风险的提案，该提案将对欧洲飞机供应链的数字化转型做出重大贡献。

Direct aviation emissions accounted for 3.8% of total CO2 emissions and 13.9% of the emissions from transport in the EU in 2017, making it the second biggest source of greenhouse gas emissions after road transport. In addition, the growing amount of air traffic means that many EU citizens are still exposed to high noise levels. Intensified research and innovation activities are therefore needed to reduce all aviation impacts and emissions (CO2 and non-CO2, noise, manufacturing) for the EU to reach its policy goals towards a net zero greenhouse gas emissions by 2050. One of the main levers to decrease CO2 emissions is to reduce the airframe structural weight. As an answer, FALCON’s ambition is to enhance the design capabilities of the European industrial aircraft sector, focusing on fluid structure interaction (FSI) phenomena to improve the aerodynamic performances of aircraft (unsteady loads). Specifically, FALCON aims to develop high-performance, predictive and multi-disciplinary tools for FSI in aeronautics, in order to reduce the aeroacoustics and aeroelastic instabilities using multi-fidelity optimization. This will also benefit to specific noise emissions generated by flexible and mobile airframe structures when exposed to both low and high-speed fluid flows. To achieve its ambitious goal, FALCON assembles a unique interdisciplinary environment of fifteen public and private institutions and their affiliated entities (from renowned research institutions to SMEs and aircraft high-tier suppliers and integrators) to cover all the required scientific and know-how expertise. Building upon three industrial testcases and tight links with key European partnerships such as Clean Aviation, FALCON delineates a high-impact/ low-risk proposal that will significantly contribute to the digital transformation of the European aircraft supply chain.
