Day 1, Session 4: Airframe Integration & Development: Delivering Zero-Emission Propulsion
Speakers:
Moderator - Dominic Perry, Deputy Editor, Flight International/FlightGlobal
Gabriele Teofili, Managing Director, ZeroAvia
Phil Ansell, Director, Center for Sustainable Aviation, University of Illinois
Jacqueline Castle, CTO, Aerospace Technology Institute
Retrofit of innovative zero-emission engines potentially offers a quicker route to market, and thus a more imminent solution to tackle a slice of aviation’s carbon emissions. But cleansheet design can maximize the impact of hydrogen propulsion solutions, and will be essential for aircraft of certain size.
How far can retrofit solutions go and where is the limit? What promising airframe design efficiencies will we see enhancing the benefits of hydrogen flight? Can all aircraft ultimately fly on hydrogen?
