摘要

The extreme weather events this year have highlighted the need to decarbonise the world's economies as soon as possible and a green Airbus A380 derivative is aviation's solution for one team of academics. In September 2020, Airbus revealed three hydrogen-fuelled aircraft concepts which it said could enter service by 2035 but none of them were like the European double-decker. They were: a 200-passenger blended wing body (BWB) type, a 100-passenger turboprop regional aircraft and a more conventional A321 family-like 200-passenger turbofan design with a very high aspect ratio wing - it is very wide in comparison with the length of the fuselage. In June this year, the media reported that Airbus had told the European Commission in a closed briefing that hydrogen aircraft would not be widely used until 2050. Aircraft entering service in the 2030s and their wide usage by 2050 are not contradictory claims but three Cranfield University researchers decided to examine how 2035 could realistically be achieved. Long before June this year, they had asked themselves the question: how could a first-generation hydrogen-powered airliner be realised faster and their answer was the Airbus A380. Writing for the International Society for Air Breathing Engines (ISABE), a broad description of the Cranfield thermal power and propulsion engineering researcher's A380 solution is storing the hydrogen tanks in the upper or lower decks. A third concept has the tanks distributed on different levels within the aircraft. The lower deck option has a range of 4,800nm and could carry 332 passengers. Upper deck storage would have 3,300nm range and 388 passengers. The third option would have up to 232 passengers and a 5,500nm range.
