Front cover: HERA is a 70-seat hybrid-electric airliner concept from Electric Aviation Group.. (EAG) @aerosociety i Find us on LinkedIn f Find us on Facebook www.aerosociety.com SEPTEMBER 2020 13 Blueprint INTELLIGENCE / ANALYSIS / COMMENT The path to zero-carbon While the current configuration shows four propulsors or engines of an unknown type, EAG says that the HERA has been future- proofed to be converted to all-electric or alternative zero-carbon propulsion systems before 2030 as the technology matures. Range will initially be 800nm but expand to 1,200nm as battery density improves. AIR TRANSPORT English electric excites On 20 July a previously unknown Bristol-based start-up, English Aviation Group (EAG), revealed a concept for a 70-seat hybrid-electric regional airliner (HERA) – the largest hybrid aircraft yet. The group, which includes ex-Airbus veterans, says that the airliner could be ready by 2028. The aircraft would feature STOL capability and a ‘whisper-quiet’ acoustic profile to enable utilisation at more airfields than can be used by existing regional airliners. EAG also say that the design could be adapted to take advantage of alternative propulsion technology as it matures to enable zero-carbon flight. The company is aiming to test its technology on a Dash 7/8 size demonstrator in the next four years. EAG believes development of HERA will cost $5bn, with the potential of being a first mover in a $4.4tn market and delivering 50% higher revenues for operators. Electric Aviation Group Electric Aviation 4 AEROSPACE Specifications Passengers 70 MTOW 55,000lb Cruise speed 275kt Range 800nm initially Sized for growth EAG believes that current 19-seat concepts for hybrid-electric/electric regional aircraft are too small to meet the demands of green mass transportation – and has thus picked a 70-seat airliner. It also forsees the aircraft being offered in a quick-change passenger/ freight version, to allow passenger flights during the day and cargo operations during the night. Ultra-quiet operations will enable it to be operated around the clock. GATOR-aid EAG says the HERA would Green machine use Gear Assisted Take- Off Run (GATOR) to give EAG estimates that HERA will be able to rapid acceleration for a achieve: quick lift-off, reducing the 90% reduction in NOx emissions overall energy 70% reduction in CO2 emissions requirements. Meanwhile, 65% reduction in noise pollution the aircraft would also be able to regenerate power for its 3.5ton lithium-ion batteries while in flight, reducing turn-around time. EAG has already filed 25 patents for the technology used in HERA.
