Descripción del proyecto
Un sistema de propulsión reduce la huella de carbono de la aviación
El aumento el tráfico aéreo incrementará las emisiones acústicas y de combustión, lo que empeorará el impacto ambiental de la aviación. El equipo del proyecto HOPE, financiado con fondos europeos, desarrollará un sistema integrado de propulsión para aeronaves con dos motores turbohélice multicombustible con índice de derivación ultra alta y una unidad auxiliar de energía y propulsión auxiliar basada en pilas de combustible, que impulsa un propulsor de ingestión de capa límite de popa basado en la configuración de aeronave de fuselaje y alas. Este sistema reducirá las emisiones acústicas y de combustión durante el aterrizaje y el despegue, permitirá reorganizar la configuración actual de las aeronaves y eliminará el riesgo del uso de hidrógeno solo en las configuraciones de aeronaves de fuselaje y alas existentes. En HOPE se favorecerá una transición energética fluida del sector gracias a varias tecnologías ecológicas de propulsión con diferentes niveles de madurez.
Objetivo
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.
