Airbus and CFM International are to collaborate on a hydrogen demonstration program that will take flight around the middle of this decade using an A380 superjumbo.
The objective is to ground and flight test a direct combustion engine fueled by hydrogen, in preparation for entry-into-service of a zero-emission aircraft by 2035.
The demonstration will use an A380 flying testbed equipped with liquid hydrogen tanks prepared at Airbus facilities in France and Germany.
Airbus will define the hydrogen propulsion system requirements, oversee flight testing, and provide the A380 platform to test the hydrogen combustion engine in cruise phase.
CFM International will modify the combustor, fuel system, and control system of a GE turbofan engine to run on hydrogen.
The engine, which is assembled in the US, was selected for this program because of its physical size, advanced turbomachinery, and fuel flow capability.
It will be mounted along the rear fuselage of the flying testbed to allow engine emissions, including contrails, to be monitored separately from those of the engines powering the aircraft. CFM will execute an extensive ground test program ahead of the A380 flight test.
“This is the most significant step undertaken at Airbus to usher in a new era of hydrogen-powered flight since the unveiling of our ZEROe concepts back in September 2020,” said Sabine Klauke, Airbus Chief Technical Officer.
“By leveraging the expertise of American and European engine manufacturers to make progress on hydrogen combustion technology, this international partnership sends a clear message that our industry is committed to making zero-emission flight a reality.”
“Hydrogen combustion capability is one of the foundational technologies we are developing and maturing as part of the CFM RISE Program,” said Gaël Méheust, president & CEO of CFM.
“Bringing together the collective capabilities and experience of CFM, our parent companies, and Airbus, we really do have the dream team in place to successfully demonstrate a hydrogen propulsion system.”
