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) Minimizes 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) Retrofits the existing aircraft configuration, allowing 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 (kero/SAF + H2) 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 kero/SAF + H2 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.
