The Anonymous Widower

Airbus, Rolls-Royce, EasyJet Headline Formation Of UK Hydrogen Alliance

The title of this post, is the same as that of this article from Future Flight.

These two paragraphs outline the story.

A group of leading companies in the UK aviation and renewable energy sectors including EasyJet, Rolls-Royce, and Airbus has established the Hydrogen in Aviation (HIA) alliance to accelerate the delivery of zero-carbon aviation, the companies said Tuesday. HIA, whose partners also include Ørsted, GKN Aerospace, and Bristol Airport, said decarbonization efforts involving hydrogen should assume more urgency at a time when sustainable aviation fuel and batteries have drawn so much of the sector’s attention.

Working with government, local authorities, and the aviation and hydrogen sectors, the group plans to draw on members’ expertise to propose “a clear and deliverable pathway” to achieving hydrogen-powered aviation. Efforts center on clearing a pathway for preparing the needed infrastructure as well as policy, regulatory, and safety frameworks.

This Airbus infographic describes the aircraft in Airbus’s ZEROe project.

Discover the three zero-emission concept aircraft known as ZEROe in this infographic. These turbofan, turboprop, and blended-wing-body configurations are all hydrogen hybrid aircraft.

These are my thoughts.

Do The ZEROe Turboprop And The ZEROe Turbofan Have Similar Hydrogen Systems?

This is Airbus’s summary of the design of the ZEROe Turboprop

Two hybrid-hydrogen turboprop engines, which drive eight-bladed propellers, provide thrust. The liquid hydrogen storage and distribution system is located behind the rear pressure bulkhead

This screen capture taken from an Airbus video, shows a rear view of the plane.

Note the sizeable cone-shaped rear end to the fuselage with no windows.

ZEROeTurbofan

Note how there are no windows at the back of the fuselage, as the hydrogen tank doesn’t need them.

It looks to me, that similar cone-shaped tanks for hydrogen, customised for each aircraft could be placed behind the rear bulkhead.

There would probably be space for any pumps needed to distribute the hydrogen to the engines.

All the stored hydrogen and its gubbins could be safely sealed behind the rear bulkhead.

I am fairly certain that the ZEROe Turboprop and the ZEROe Turbofan will have similar hydrogen systems.

Do The ZEROe Turboprop And The ZEROe Turbofan Have Auxiliary Power Units?

The auxiliary power unit or APU in an aircraft that provides energy for functions other than propulsion.

In Airbus To Trial In-flight Auxiliary Power Entirely Generated By Hydrogen, I wrote about Airbus’s development of APU’s based on fuel cells and running on hydrogen.

This surely could be a way to go.

  • A battery could store power.
  • Fuel cells are proving to be reliable.
  • The plane would have two independent electrical systems.

Power would always be available for the cockpit, flying controls and to restart the engines, just as it is in any airliner today.

Do The ZEROe Turboprop And The ZEROe Turbofan Have The Same Cockpit?

The cockpits of the A 320 neo and the A 320 ceo seem to have a similar profile, but the cockpit of the ZEROe Turbofan seems to have been reprofiled.

In ZEROe – Towards The World’s First Zero-Emission Commercial Aircraft, I showed these front on views of the cockpits of the ZEROe Turboprop and ZEROe Turbofan.

I questioned if the two cockpits were related.

  • A single cockpit for both aircraft would surely ease manufacture, maintenance and pilot training.
  • I’m no aerodynamicist, but it certainly looks that the new cockpit will reduce drag and fuel consumption.

This common cockpit concept was used for the Boeing 757 and the Boeing 767 in the 1980s, so it is not a new concept.

Although the cockpit, appears to be being used in the ZEROe for the first time, I would expect it is already under development and might feature in any later version of the A 320 neo.

Do Airbus Have A Preferred Development Order?

Consider.

  • My product development experience indicates that the development of the ZEROe Blended-Wing Body will involve more flight testing and aerodynamic checks than the other two aircraft, so I would make it the last aircraft to enter service.
  • The ZEROe Turboprop appears to be a development of the ATR 72.
  • The ZEROe Turbofan appears to be a development of an A 320 neo.
  • The ZEROe Turboprop and ZEROe Turbofan would appear to have similar designs of cockpit, hydrogen systems and auxiliary power units.
  • It looks to me that either of the ZEROe Turboprop or ZEROe Turbofan could be developed first.

I would develop the ZEROe Turboprop first, as it is the smaller aircraft.

Why Bristol Airport?

This page on the Airbus web site is entitled Airbus In The United Kingdom, where this is the first paragraph.

Building on a proud 100-year British aviation heritage, Airbus is part of the very fabric of the UK – which is one of the company’s four home markets, alongside France, Germany and Spain. Its 11,000-strong UK workforce is part of a global family of 125,000 employees.

This is said under Commercial Aircraft.

The sites at Filton and Broughton design, test and manufacture the wings for all Airbus’ A320 family, A330 and A350 commercial aircraft, directly sustaining more than 8,000 full-time jobs and hundreds of apprenticeships.

A220 family wings are designed and built by Spirit AeroSystems in Belfast, Northern Ireland.

Broughton has a proud tradition of aerospace manufacturing dating back 80 years, having supplied the RAF with vital aircraft during the Second World War. Employing almost 5,000 people, Broughton is a global centre of excellence for manufacturing and delivers over 500 wing sets per year for the A320 family, A330 and A350. Airbus has invested more than £2 billion in the Broughton plant over the past 10 years.

Core activities at Filton, where an additional 3,000 people work, are the design, engineering and support for Airbus wings, fuel systems and landing gear systems. Teams also work on aerodynamics research, development and test facilities, including our future zero-emissions programme, ZEROe, while wings for the A400M transporter are assembled on site.

It would appear that Filton in Bristol, is a very important part of Airbus’s operations in the UK.

  • It appears to have major responsibility for all Airbus wings except the smallest.
  • It has a large responsibility with respect to the ZEROe family of aircraft.
  • Filton Airfield is now closed.
  • Filton can do substantial assembly if required.

So was it just a logical decision to phone up Bristol Airport and ask, if they’d like to join the project?

In addition.

  • Bristol Airport has a 2000 metre East West asphalt runway.
  • The airport can handle a Boeing 787 Dreamliner and Airbus A330.
  • It is the eighth busiest airport in the UK.
  • It is a busy general aviation airfield.
  • There is plenty of electricity in the area and Hinckley Point C will open down the road in a couple of years.

Bristol Airport is probably typical of many provincial airports around the world.

Why EasyJet?

These paragraphs from the Future Flight article help to explain.

“There is no doubt that the UK has the potential to become a world leader in hydrogen aviation, which could bring with it a £34 billion per annum boost to the country’s economy by 2050, but in order to capture this opportunity, rapid change is needed and the time to act is now,” said Johan Lundgren, CEO of EasyJet and HIA’s first chairman.

“We must work together to deliver the radical solutions required for a hard-to-abate industry like aviation so we can protect and maximize the benefits that it brings to the UK economy and society and that we know British consumers want to be preserved.”

Under its Zero-E program, Airbus aims to bring to market the first hydrogen-powered narrowbody commercial airplane by 2035. Separately, a partnership between Rolls-Royce and EasyJet signed last year saw the companies test hydrogen fuel in gaseous form in an adapted AE2100-A turbine, the engine that powers the Saab 2000 regional airliner. The November 2022 test, which used hydrogen produced in the Orkney Islands by the European Marine Energy Centre using renewable energy, marked the first run of a modern engine using hydrogen.

EasyJet seems to be enthusiastic about hydrogen and their CEO will be the HIA’s first chairman.

Note.

  1. There are nine routes under 400 miles, which might enable a round trip without refuelling in a ZEROe Turboprop.
  2. There are nine routes under 800 miles, which might enable a round trip without refuelling in a ZEROe Turbofan.
  3. There are only four routes over 2000 miles, which might make a single trip difficult in a ZEROe Turbofan.
  4. Bristol and Toulouse is a convenient 569 miles for Airbus and its employees, customers and contractors.

It does appear that, EasyJet’s routes fit the 1000 mile range of a ZEROe Turboprop and the 2000 mile range of a ZEROe Turbofan exceedingly well.

Conclusion

Bristol will be important in the development of Airbus’s three ZEROe aircraft.
