Climate-neutral aviation will require the use of alternative fuels such as Green Hydrogen and Sustainable Aviation Fuel (SAF) combined with the power density of an ultra-efficient gas turbine engine for the Small and Medium Range (SMR) market which corresponds to approximately 50% of the current share of air transport emissions. Rolls-Royce (represented within the HEAVEN project by RR-UK, RR-D and ITP) supported by key UK and European academia, industry and research centres are currently developing a new generation of very high bypass ratio geared engine architecture called UltraFan® which was started in 2014. From the beginning this ducted engine architecture has been designed to be scalable and meet the needs both of widebody and SMR markets. To achieve the necessary 20% fuel burn reduction Rolls-Royce proposes to significantly evolve the UltraFan design into UltraFan H2. The evolved engine architecture design will take the next steps in improving the efficiency of the gas turbine, take advantage of the properties of net zero carbon fuels such as Hydrogen to improve efficiency, combining this with Hybrid electric technology to reduce wasted energy. Numerous innovative enabling technologies already at TR3 will be incorporated into this new architecture to improve the gas turbine efficiency. Together with work proposed on Hydrogen in CAVENDISH (HRA-01) and Hybrid Electric in HE-ART (HER-01) Clean Aviation proposals in conjunction with activities in national and regional programmes, this will be synergistically combined to validate up to TRL6 the highly innovative UltraFan H2 design to support a 2035 EIS. HEAVEN brings together a highly specialised European industrial and academic consortium already strongly involved and familiar with the UltraFan programme. Additionally, the partner easyJet, European airline operator who have the largest fleet of European manufactured SMR aircraft operating in Europe will bring an in depth knowledge of operational requirements.

气候中立航空将需要使用替代燃料，如绿色氢气和可持续航空燃料(SAF)，并结合中小型(SMR)市场的超高效燃气轮机发动机的功率密度，这相当于目前航空运输排放的约50%。劳斯莱斯(由RR-UK、RR-D和ITP代表的HADAY项目)在英国和欧洲的主要学术界、工业和研究中心的支持下，目前正在开发名为UltraFan®的新一代超高旁路比齿轮发动机架构，该架构始于2014年。从一开始，这种管道式发动机架构就被设计为可扩展并满足宽体和SMR市场的需求。为了实现必要的20%的燃料消耗减少，劳斯莱斯建议将UltraFan的设计显著改进为UltraFan H2。进化后的发动机架构设计将在提高燃气轮机效率方面采取下一步行动，利用氢等净零碳燃料的特性来提高效率，并将其与混合动力技术相结合，以减少能源浪费。TR3已有的众多创新启用技术将被整合到这个新架构中，以提高燃气轮机的效率。连同在卡文迪什(HRA-01)中的氢气和HE-ART(HER-01)中的混合电动拟议的工作，以及国家和区域计划中的活动，这将协同结合，以验证高达TRL6的高度创新的UltraFan H2设计，以支持2035年的环境影响报告书。天堂汇聚了一个高度专业化的欧洲工业和学术财团，该财团已经强烈参与并熟悉UltraFan项目。此外，拥有在欧洲运营的最大欧洲制造SMR飞机机队的欧洲航空公司合作伙伴easyJet将带来对运营要求的深入了解。
