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 first flight of an aircraft fueled solely by hydrogen became a reality on Sunday, June 19, 1988, at Fort Lauderdale Executive Airport. The aircraft was flown by Mr. William H. "Bill" Conrad, and the event was witnessed and recorded by the National Aeronautics Association's representative...
environmental impact, and recent technology developments. They efficiently convert hydrogen into electricity with a low weight, the latter of which is of fundamental importance to application on board aircraft. Recent innovations, such as those in March 2024 from NREL, have managed to increase...
A hydrogen fueled jet engine for hypersonic aircraft. The compressor of the jet engine is driven directly by a dual-acting rotary piston engine. Heated, high pressure hydrogen is delivered to the rotary piston engine for expansion therein. The crankshaft of the rotary piston engine is attached di...
future integration of new technologies like hydrogen and electric aircraft. The partnering companies are global leaders in the development of hydrogen-electric flights, having already conducted hydrogen-fueled test flights and planning to launch hydrogen-electric aircraft between the mid-2020s and ...
A groundbreaking partnership is taking off between Airbus and Toshiba Corp. to explore the potential of superconducting technology for the future development of hydrogen-powered aircraft.
While hydrogen can also be used directly as a fuel in a gas turbine, it is likely to start in the shorter haul segments, where the aircraft range is shorter. Given volume limitations attached to the storage of hydrogen and the limited power density of fuel cells, for long range, SAF fuel...
GKN Aerospace has successfully ground tested a liquid hydrogen fuel system for aircraft. The demonstrator was designed, built and tested by GKN and UK-based Filton Systems Engineering to investigate the feasibility of using a liquid hydrogen fuel source in a search and rescue dro...
Rolls-Royce is testing liquid hydrogen pumps able to deal with the low temperatures and pressures needed for future hydrogen-fueled aircraft propulsion systems. Rolls-Royce is working with airline easyJet to develop hydrogen combustion aero engines. The engines will be suitable for ...
the choice of hydrogen storage for trucks could determine whether LH2will be an everyday road vehicle fuel or principally used only in aircraft. The use of LH2would favor a centralized H2infrastructure for efficient liquefaction, whereas a GH2infrastructure would very likely have lower ultimate cost...
