Description du projet
Un système de propulsion réduit l’empreinte carbone de l’aviation
L’augmentation du trafic aérien entraînera une hausse de la consommation de carburant et des émissions acoustiques, ce qui aggravera les effets de l’aviation sur l’environnement. Le projet HOPE, financé par l’UE, fournira un système intégré de propulsion d’aéronef comprenant deux turbopropulseurs à taux de dilution ultra-élevé (UHBR) multicarburants et un groupe auxiliaire de propulsion et de puissance basé sur une pile à combustible (FC-APPU) entraînant un propulseur d’ingestion de la couche limite arrière (BLI) basé sur la configuration d’un aéronef à voilure tubulaire Ce système réduira les émissions de combustion et de bruit lors de l’atterrissage et du décollage, remettra en état la configuration actuelle de l’avion et éliminera les risques liés à l’utilisation de l’hydrogène uniquement dans les configurations existantes d’avions à voilure tubulaire. HOPE permettra une transition énergétique en douceur du secteur grâce à plusieurs technologies de propulsion vertes à différents niveaux de maturité.
Objectif
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)retrofits the 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.
