Direct Combustion of Hydrogen in Aero-Engines "CAVENDISH"

根据欧洲绿色协议到2050年在航空业实现碳中和的目标，将研究与直接（100%氢气）燃烧系统相关的突破性技术，并将其原型化并集成到CAVENDISH项目的现代捐赠航空发动机上进行地面测试（从2024年底开始）。这种液氢航空发动机测试将是欧洲的第一次，也是进一步飞行演示的基石，最终导致产品开发，旨在满足欧洲和行业对2035年商用、大众运输、氢燃料飞机进入服役（EIS）的雄心。CAVENDISH的第二个目标将是与几家成熟的飞机制造商和一个补充的型号认证组织一起进行系统和动力装置飞机集成，以定义认证途径并制定允许飞行的路线。这一活动将直接有利于清洁航空方案下一阶段预定进行的捐助发动机飞行试验。CAVENDISH还将探索双燃料燃烧器系统（能够在100%氢气和100% SAF上运行）和低温压缩罐系统形式的替代技术。这两种技术都将提供灵活性，并可以简化氢在航空中的引入。CAVENDISH汇集了航空、动力和推进、燃烧、燃料和控制系统以及飞机领域的欧洲领先专业组织。它建立在来自英国、德国、法国和荷兰的多个国家技术计划的基础上，实际上是将这些技术途径结合并加速为液氢燃烧航空发动机的早期示范和第一个最小可行产品（MVP）。该项目还与其他清洁航空呼吁中的活动有关，特别是关于SMR和认证活动，特别是HEAVEN和CONCERTO项目提案。

In line with the European Green Deal target of reaching carbon neutrality in the aviation industry by 2050, breakthrough technologies related to direct (100% hydrogen) combustion systems will be researched, prototyped and integrated onto a modern donor aeroengine for ground testing (starting in late 2024) in Project CAVENDISH. This aeroengine test on liquid hydrogen will be a first of a kind in Europe and the cornerstone to further in-flight demonstration, eventually leading to product development aimed at meeting Europe’s and the industry’s ambition for the entry in service (EIS) of commercial, mass-transport, hydrogen-fuelled aircraft in 2035. CAVENDISH’s second objective will be to work on system and powerplant aircraft integration with several established airframers and a supplemental type certificate organisation to define certification pathways and formulate a route to permit to fly. This activity will directly benefit the flight test of the donor engine scheduled for the next phase of the Clean Aviation programme. CAVENDISH will also explore alternative enabling technologies in the form of a dual fuel combustor system (capable of operating on 100% hydrogen and 100% SAF) and in the form of a cryo-compressed tank system. Both these technologies will offer flexibility and could ease the introduction of hydrogen in aviation. CAVENDISH brings together expertise-leading European organizations in aeronautics, power and propulsion, combustion, fuel and controls systems and aircraft. It builds on multiple national technology programmes heralding from the UK, Germany, France and the Netherlands, and is in effect the marriage and acceleration of these technology pathways into an early demonstration and a first minimum viable product (MVP) of a liquid hydrogen combusting aeroengine. The project is also connected to activities in other Clean Aviation calls, on SMR and Certification activities specifically, notably project proposals HEAVEN and CONCERTO.
