Abstract:

Hydrogen aircraft is an important development direction of the aviation industry to achieve green energy transformation. Airbus, Universal Hydrogen and other institutions are conducting research on hydrogen aircraft. Hydrogen fuel cell regional aircraft is one of the hottest development directions at the moment. Hydrogen-powered DHC-8-300 and Dornier 228 have completed their first flight and are expected to be put into commercial use by 2027. But now, the research on hydrogen regional aircraft in China mostly stays in technical exploration, and there are few studies on the overall design scheme of full-size regional aircraft platform. In this paper, a retrofit design of hydrogen fuel cell power based on the turboprop regional aircraft platform is proposed, and the performance of the hydrogen fuel cell aircraft is analyzed by simulation method. The regional aircraft with modified hydrogen fuel cell uses a hybrid energy system of liquid hydrogen fuel and lithium battery, powered by electric motors. The main disadvantages of hydrogen aircraft compared to jet aircraft are lower maximum range, seating capacity and higher operating costs. The payload of the hydrogen aircraft is equal to that of the jet aircraft. The flight efficiency of hydrogen aircraft is higher, and the carbon emissions are extremely low. With technological advances, hydrogen aircraft is expected to match or even surpass the performance of jet aircraft.
