SWITCH aims to answer the challenge of climate-neutral short-medium range air transport by developing a revolutionary sustainable gas turbine propulsion system – the hybrid Water-Enhanced Turbofan (hybrid WET). It boosts WET technology with hybridization (Electrical Aircraft Propulsion – EAP) to improve energy efficiency by 25% and reduce climate impact by 75% (using net zero-CO2 sustainable aviation fuel, 50% with conventional Jet-A kerosene) compared to a state-of-the-art engine. It is the only concept to significantly reduce all three major warming effects on our climate: CO2 through unmatched efficiency, NOx through water injection in the combustor, and contrails through particle removal and water recovery. Local air quality and noise levels around airports are improved through electric taxiing. The hybrid WET is fully compatible with drop-in SAF and could also be adapted to burn hydrogen. It addresses all climate-notable market segments: Short-, medium- and long-range. The SWITCH project will meet this challenge with a global consortium, through an unprecedented programmatic effort between airframer, engine and system OEMs, key tier 1 suppliers and leading researchers in combustion and propulsion, leveraging relevant and effective synergies between European and national programs. SWITCH will mature the hybrid WET’s two key innovation concepts by 2025: The WET engine to technology readiness level (TRL) 4 through validation of its key enabling technologies and the EAP system to TRL 5 through flight-ready engine ground demonstration of the full propulsion system. Results from SWITCH will reinforce confidence in the climate reduction potential of the hybrid WET propulsion system and form the technological foundation to achieve TRL 6 by 2030. This will enable the innovation to enter into the market by 2035 on a new short-medium range aircraft to significantly reduce aviation’s climate impact towards the European Green Deal’s goal of climate neutrality by 2050.

该公司旨在通过开发一种革命性的可持续燃气涡轮机推进系统-混合水增强涡轮风扇（混合WET）来应对气候中性中短程航空运输的挑战。与最先进的发动机相比，它通过混合动力技术（电动飞机推进- EAP）提升了WET技术，将能源效率提高了25%，并将气候影响减少了75%（使用净零二氧化碳可持续航空燃料，50%使用传统的Jet-A煤油）。这是唯一一个能够显著减少三大气候变暖效应的概念：通过无与伦比的效率减少二氧化碳，通过在燃烧室中注水减少氮氧化物，通过颗粒去除和水回收减少尾迹。电动出租车改善了机场周围的空气质量和噪音水平。混合WET与插入式SAF完全兼容，也可用于燃烧氢气。它解决了所有气候显著的细分市场：短期，中期和长期。该项目将与一个全球联盟一起应对这一挑战，通过飞机制造商，发动机和系统OEM，主要一级供应商以及燃烧和推进领域的领先研究人员之间前所未有的计划性努力，利用欧洲和国家计划之间的相关和有效协同作用。到2025年，波音公司将使混合动力WET的两个关键创新概念成熟：通过验证其关键使能技术，将WET发动机提升到技术准备水平（TRL）4，通过飞行准备发动机地面演示完整推进系统，将EAP系统提升到TRL 5。研究结果将增强人们对混合WET推进系统的气候减排潜力的信心，并为到2030年实现TRL 6奠定技术基础。这将使创新能够在2035年之前进入市场，用于新的中短程飞机，以显著减少航空对欧洲绿色协议到2050年实现气候中立目标的气候影响。
