Fuel cells would make sense only for general aviation and small commuter aircraft as their engine efficiency is less than half of large gas turbines, but not for usual single or twin-aisle airliners.[3] The efficiency of a hydrogen-fueled aircraft is a trade-off of the larger wetted area,...
the amount of usable cabin space, as the fuel tank takes up 65% of the aircraft's internal volume. Despite the large LH2 tank weight of about l4,865lb, due to the low fuel weight the aircraft's takeoff gross weight is only ll3,646lb, about 80% of the current petroleum-fueled P-...
“Green hydrogen, made with electricity from renewable sources is the major factor for sector coupling in the energy sector. Fuel cells, fueled with this green hydrogen, will play a key role in the decarbonisation of drive systems and power supply. No other technology offers such high reliabil...
The aviation industry has had something of an on-off relationship with hydrogen as a fuel for airplanes over the years. In the early 2000s, Airbus’s Cryoplane initiative examined the feasibility of a liquid hydrogen-fueled aircraft, while in 2008Boeingflew the world’s first hydrogen-powered ...
Despite this early recognition, the design of the tanks is nowadays still seen as crucial as aircraft tanks differ significantly from existing tanks in the automotive or aerospace sector. To enable system level feasibility studies of hydrogen fueled aircraft, a preliminary design model for aircraft ...
Liquid hydrogen fuel system design and demonstration in a small long endurance air vehicle A liquid hydrogen (LH2) fueled small unmanned aircraft has been demonstrated.LH2 fuel can provide longer endurance than gaseous hydrogen, depending on heat... RO Stroman,MW Schuette,K Swider-Lyons,... -...
A preliminary design is reported. Also, the paper contains a description of testing activities related to experimental flights of an all-electric general aviation aircraft fueled by hydrogen. Great importance has been given to the testing phase of the prototype and examples of each testing stage ...
