The ICAO Post-COVID forecasts estimate a 2.4%-4.1% increase for a low to high revenue passenger-kilometres growth rate. Air traffic growth inevitably increases aviation's combustion and acoustic emissions, hence aggravating aviation's environmental impact locally and globally. HOPE will deliver an integrated aircraft propulsion system comprising two multi-fuel ultra-high bypass ratio (UHBR) turbofan engines, a fuel cell based auxiliary propulsion and power unit (FC-APPU) driving an aft boundary layer ingestion (BLI) propulsor based on tube-wing aircraft configuration. The HOPE system: 1)minimises the combustion and noise emissions during landing and takeoff (LTO), hence the impact on air quality and noise annoyance near airports, without the trade-off of cruise emissions; 2)retrofitsthe existing aircraft configuration, allowing the substantial emission reduction to be achieved within a short time; 3)de-risks the use of hydrogen solely in existing tube-wing aircraft configurations; 4)smoothens aviation’s energy transition through assessment and exploitation of several greener propulsion technologies at different maturity level. HOPE emission goals consist of LTO NOx: -50%, CO: -50%, soot: -80%, perceived noise: -20% (~3 dB per operation), and climate impact: -30%, compared to state-of-the-art technology in 2020 (A320neo). To this end, HOPE will: 1)Design an integrated aircraft propulsion system accommodating multi-fuel (kerosene/sustainable aviation fuel +hydrogen) UHBR turbofan engines, FC-APPU, and an aft BLI propulsor; 2)Explore the novel idea of combining a BLI propulsor with FC-APPU for zero-emission taxiing; 3)Model, experiment, and demonstrate for the first time a low emission multi-fuel combustion technology burning H2+kerosene/SAF for future UHBR turbofan engine; 4)Assess societal impact, environmental burden, and cost benefits of the reduced noise and emissions by HOPE technology; 5)Formulate policy and recommendations to introduce HOPE technology.

国际民航组织 (ICAO) 预测，新冠疫情后，收入客运公里增长率将从低到高增长 2.4%-4.1%。空中交通的增长不可避免地增加了航空的燃烧和声排放，从而加剧了航空对当地和全球环境的影响。 HOPE将提供集成飞机推进系统，包括两台多燃料超高涵道比（UHBR）涡轮风扇发动机、一个基于燃料电池的辅助推进和动力装置（FC-APPU），驱动基于管翼飞机配置的后边界层吸入（BLI）推进器。 HOPE系统：1）最大限度地减少着陆和起飞（LTO）期间的燃烧和噪音排放，从而最大限度地减少对机场附近空气质量和噪音烦恼的影响，而无需权衡巡航排放； 2）对现有飞机配置进行改造，可在短时间内实现大幅减排； 3）降低现有管翼飞机配置中仅使用氢气的风险； 4）通过评估和开发不同成熟度的多种绿色推进技术，平滑航空能源转型。与 2020 年最先进的技术 (A320neo) 相比，HOPE 排放目标包括 LTO NOx：-50%、CO：-50%、烟尘：-80%、感知噪音：-20%（每次操作约 3 dB）和气候影响：-30%。为此，HOPE将： 1）设计一个集成的飞机推进系统，可容纳多燃料（煤油/可持续航空燃料+氢气）UHBR涡扇发动机、FC-APPU和机尾BLI推进器； 2）探索BLI推进器与FC-APPU相结合实现零排放滑行的新思路； 3）首次对未来UHBR涡扇发动机燃烧H2+煤油/SAF的低排放多燃料燃烧技术进行建模、实验和论证； 4）评估HOPE技术减少噪音和排放的社会影响、环境负担和成本效益； 5)制定引进HOPE技术的政策和建议。
