Airbus (Toulouse, France) revealed on Sept. 21 three concepts for what the company says is the world’s first zero-emission commercial aircraft which could enter service by 2035. These concepts, says Airbus, each represent a different approach to achieving zero-emission flight, exploring various technology pathways and aerodynamic configurations in order to support the its ambition of leading the way in the decarbonization of the entire aviation industry.
All of these concepts rely on hydrogen as a primary power source — an option which Airbus believes holds promise as a clean aviation fuel and is likely to be a solution for aerospace and many other industries to meet climate-neutral targets.
The three concepts — all codenamed “ZEROe” — for the first climate neutral zero-emission commercial aircraft include:

- A turbofan design (120-200 passengers) with a range of 2,000+ nautical miles, capable of operating trans-continentally and powered by a modified gas-turbine engine running on hydrogen, rather than jet fuel, through combustion. The liquid hydrogen will be stored and distributed via tanks located behind the rear pressure bulkhead.

A turboprop design (up to 100 passengers) using a turboprop engine instead of a turbofan and also powered by hydrogen combustion in modified gas-turbine engines, which would be capable of traveling more than 1,000 nautical miles, making it a perfect option for short-haul trips.

“The transition to hydrogen, as the primary power source for these concept planes, will require decisive action from the entire aviation ecosystem,” says Guillaume Faury, Airbus CEO. “Together with the support from government and industrial partners we can rise up to this challenge to scale-up renewable energy and hydrogen for the sustainable future of the aviation industry.”
In order to tackle these challenges, says Airbus, airports will require significant hydrogen transport and refueling infrastructure to meet the needs of day-to-day operations. Support from governments will be key to meet these ambitious objectives with increased funding for research and technology, digitalization, and mechanisms that encourage the use of sustainable fuels and the renewal of aircraft fleets to allow airlines to retire older, less environmentally friendly aircraft earlier.
The matrix binds the fiber reinforcement, gives the composite component its shape and determines its surface quality. A composite matrix may be a polymer, ceramic, metal or carbon. Here’s a guide to selection.
Composite structures are more vulnerable to damage than metal, but today's LSP products offer proven protection.
Focused on optimizing traditional hand layup, nacelle and thrust reverser manufacturers cast an eye on future use of automation and closed molding.
