Electric Passenger Plane to be “Whisper Quiet”

July 21, 2020

Asia Times:

What’s green and carbon friendly to operate … is “whisper quiet” … can carry 70 passengers through the sky … and hardly use any fuel?

According to a British firm that unveiled the concept, it will be the largest commercial hybrid plane in the world.  

The 70-seater “hybrid electric regional aircraft” (HERA) designed by the Electric Aviation Group (EAG), a Bristol-based engineering and development firm, will feature reduced noise pollution and airborne battery regeneration, The Daily Mail reported.   

It’s a hybrid passenger plane – meaning it’s powered partly by an environmentally-friendly electric engine and partly by conventional jet fuel – with a range of 920 miles (800 nm).

According to the company, that range will be extended to 1,381 miles (1,200 nm) beyond 2030, as battery energy density improves, The Daily Mail reported.

Key information about the 70+seater HERA:

  • Whisper-quiet operation reduces noise pollution
  • Innovative airborne battery regeneration to minimise turn-around time
  • Efficient battery integration
  • Thermal management of motors and power electronics
  • Gear Assisted Take-Off Run (GATOR) gives rapid acceleration for a quick lift-off reducing energy requirements
  • Short take-off-and-landing (STOL) performance enables new route opportunities affording greater profitability to operators
  • Cabin-flex design enables passenger operation during the day and cargo operation at night
  • Suitability for operating from regional airports brings convenience to travellers and gives increased proximity to warehouses, enabling private sector cargo to optimise last-mile terrestrial logistics and delivery systems and reduce carbon emissions
  • Future-proof design to accommodate alternative energy sources if available before 2030
  • Flexibility to transform into an all-electric or carbon-neutral as the battery density improves or alternative fuels and associated powertrain technologies mature and become affordable.

The design, which is being unveiled to coincide with the opening of FIA Connect, the virtual Farnborough Airshow today, has received unequivocal support from EAG’s JetZero consortium, which includes some of the UK’s leading engineering and manufacturing organisations and senior academic advisors.

“Significant investments have been raised to develop sub-19 seat hybrid and all-electric aircraft which we believe is the wrong strategy. These small planes cannot meet the demands of mass air transportation or the requirements of decarbonisation,” commented Kamran Iqbal, founder and CEO at EAG. “Our design is for an aircraft that will initially offer 800 nautical miles range at launch in 2028, and which will be able to carry over 70 people. We will be a first mover in what is a $4.4 trillion market.”

EAG will draw on the rich heritage and strong aviation industry in Bristol when it begins production of the new aircraft for which it has already developed and filed a total of 25 patents covering a wide range of technologies. The organisation expects to initially create more than 25,000 jobs and unlock $5 billion investments in the UK aerospace industry.

“We expect this to be a great example of British design, engineering and build,” said Kamran Iqbal. “Not only will the development of the HERA help the Department of Transport accelerate its ‘Jet Zero’ carbon reduction goals, it will also help to create much needed job opportunities in the aerospace, manufacturing, engineering and services industries post-Brexit. This represents the future of both passenger and cargo flights internationally and as an opportunity for investment, it could not be better timed.”

    So that’s either 800 nanometers or 800 nautical miles….


  2. […] More and more companies jostling in the Electric flight space. I’ve reported on a few of them before. […]
