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.

气候中和航空将需要使用替代燃料，如绿色氢和可持续航空燃料（SAF），并结合中小型（SMR）市场的超高效燃气涡轮发动机的功率密度，这相当于目前航空运输排放份额的约50%。罗尔斯·罗伊斯（在HEAVEN项目中由RR-UK、RR-D和ITP代表）在英国和欧洲主要学术界、工业界和研究中心的支持下，目前正在开发新一代超高涵道比齿轮传动发动机架构，该架构名为UltraFan®，于2014年启动。从一开始，这种导管式发动机结构就被设计为可扩展的，以满足宽体和小型r市场的需求。为了实现所需的20%燃油燃烧减少，劳斯莱斯提议将UltraFan设计大幅发展为UltraFan H2。改进后的发动机结构设计将进一步提高燃气轮机的效率，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的许多创新技术将被整合到这个新架构中，以提高燃气轮机的效率。再加上卡文迪什项目氢燃料（HRA-01）和HE-ART项目混合动力（HER-01）清洁航空提案中提出的工作，以及国家和地区项目的活动，这些将协同结合起来，验证高达TRL6的高度创新的UltraFan H2设计，以支持2035年的EIS。HEAVEN汇集了一个高度专业化的欧洲工业和学术联盟，这些联盟已经强烈参与并熟悉UltraFan计划。此外，合作伙伴易捷航空是欧洲航空公司运营商，拥有欧洲最大的欧洲制造的SMR飞机机队，将带来对运营需求的深入了解。
