Descrizione del progetto
Un sistema di propulsione elettrico ibrido tinge di verde il cielo
Nessuno pensava alle emissioni di carbonio e all’ambiente durante il decollo del primo aereo commerciale nel 1914. Oggi, invece, sono una preoccupazione ben presente. Il settore dell’aviazione è soggetto a forti pressioni per ridurre del 50 % le emissioni di carbonio entro il 2050, rispetto ai livelli del 2005. In questo contesto, il progetto EFACA, finanziato dall’UE, sosterrà l’ecologizzazione del settore dell’aviazione dell’UE con il collaudo di un sistema di propulsione turbo-elettrico ibrido per un velivolo regionale a elica. Saranno collaudate celle a combustibile con un liquido tradizionale e un innovativo raffreddamento di fase. Inoltre, il progetto realizzerà i progetti preliminari per un velivolo regionale a elica da 80 posti con un’autonomia di 1 000 km e un jet di linea da 150 posti con un’autonomia di 2 000 km alimentato a idrogeno liquido.
Obiettivo
The EFACA project consists of 6 main objectives at 3 levels. Level 1 consists of three TRL3 demonstrations of technologies relevant to the greening of aviation: (WP1) bench testing of a gearbox combining input from gas turbine and electric motor for an hybrid turbo-electric propulsion system for a propeller-driven regional aircraft; (WP2) comparative testing of fuel cells with conventional liquid and novel phase cooling, to show the benefits up to 20% of the latter in higher net power, reduced heat losses, and smaller volume and weight also reengineering of fuel cell and structural components to increase power-to-weight ratio up to 80%; (WP3) static ground testing of a complete liquid hydrogen fuel system from cryogenic tank to vaporization and combustion in a wide range of operating regimes and simulation of application to the speed and altitude flight envelope of jet airliners. Level 2 consists of two preliminary designs: (WP7) an 80-seat 1000-km range regional propeller driven aircraft including design and integration of hybrid turbo-electric propulsion; (WP89) a 150-seat 2000-km range jet liner with liquid hydrogen fuel including design and integration of cryogenic tanks and fuel system. At level 3 a road map (WP10) for the achievement of the EU environmental targets for aviation synthetizing conclusions in four steps: (i) current status on (WP4) emissions and (WP5) noise versus future targets and gap to be covered; (ii) assessment of relevant technologies to cover the gaps, including (WP6) battery electric and (WP9) sustainable aviation fuels, besides hydrogen (WP7) fuel cells and (WP8) turbines; (iii) most suitable technology for each class of aircraft (light, small and medium regional, single and twin aisle jetliners), and maturation time of the technology; (iv) contribution of each aircraft class to CO2 and non- CO2 global and local emissions and noise, leading to (WP10) a comprehensive road map of actions for carbon-free or emissions-free flight.
