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 Electric Aviation Group 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. 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 use Gear Assisted Take- Green machine 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. SEPTEMBER 2020 5

AEROSPACE Civil aerospace and Covid-19 alternative. The difficult decision is when to initiate a new cycle, which might of course imply a fratricidal effect on the original product’s market. Oh, but when to take the plunge on a huge new investment, which for a modern airliner is likely to be over $10bn? So it is tempting to keep the old A PROTRACTED stager going for as long as possible. If this sounds RECESSION like the Boeing 737 family, and how the 737 MAX debacle may have been one increment too many, AND the product cycle dilemma is QED.

Duopoly is the result of having the cash and good timing The 737 MAX notwithstanding, and the A380 is probably Airbus’ equivalent failure, commercially if Airbus not technically, both Boeing and Airbus have timed new products sufficiently well to stave off credible opposition and in passing to see off established competitors to create their current market dominance (Airbus might also have had some luck in not losing out to the Boeing 787, thanks to faulty battery technology). Without wishing to overload anybody with another economic concept, this has contributed to the ‘high barriers to entry’ in the civil aerospace market. High initial costs, combined with continual R&D ‘learning’, the acquisition of soft skills such as marketing and after-sales service networks, have also encouraged the drift towards duopoly. A Embraer/YouTube similar process has produced an oligopoly in engine manufacturing and other key equipment sectors such as under carriages. State aid somewhere in this process does provide a mighty help in attacking the barriers to entry, but even this is no guarantee that a new entrant can sustain the effort long enough to become a serious contender.

But things may no longer be equal – China lurks The advent of Covid1-9 and the massive disruption it is causing to the global air transport system may yet be a Schumpeterian moment. For Boeing and Airbus, at almost any other point over the last 20 years, a major recession and its effects might have been less of a challenge (the 2008 financial crisis was one such hiccup) – expensive, yes, but not a realistic opportunity to break the duopoly. China has been knocking on the door for much of this century, but had made little real progress. Now a Covid-induced extended market disruption might just provide China with a breathing space to present a real threat to Boeing and Airbus. Of course, many countries have tried to break into the civil airliner market – as many as have exited over the years perhaps.
