GKN Invests in Parallel Paths to Aviation Sustainability
The aerostructures and engine components group is applying two approaches to developing hydrogen propulsion, as well as supporting new electric aircraft.

GKN Aerospace expects a clear path to bringing hydrogen-powered airliners into commercial service open by 2025 in terms of optimum propulsion system architectures and their effective integration with airframes. Working with multiple partners, the aerostructures and engine components specialist says it has made important discoveries from both the H2Gear and H2Jet programs, which respectively focus on hydrogen-electric fuel cell-based powertrains and direct combustion of liquid hydrogen fuel in turboprop and turbofan engines.
