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 US military has been scouting electric aircraft for new opportunities to improve performance and operational resiliency. Along with battery-electric aircraft, hydrogen fuel cell technology is also in play, as demonstrated by a small business startup called Hydroplane, helmed by a CEO with a 16-...
(e.g., pumps, valves, pressure regulators, heat exchangers, lines and fittings), modifications for turbine engines to maximize the benefit of hydrogen, safety aspects compared to kerosine and methane fueled designs, equipment and facility designs for servicing hydrogen-fueled aircraft, production ...
Toshiba Corp. has been pioneering superconductor-based technology for the last 50 years. (Asahi Shimbun file photo) 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. ...
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...
tanks to cryogenic storage solutions that allow for compact hydrogen storage with minimum weight and maximum safety. These would be the crucial hydrogen technologies, assuring competitiveness across a needed range and performance characteristics for hydrogen-fueled aircraft compared to traditional aircraft. ...
A comprehensive evaluation is conducted of the technology development status, economics, commercial feasibility, and infrastructural requirements of LH2-fueled aircraft, with additional consideration of hydrogen production, liquefaction, and cryostorage methods. Attention is given to the effects of LH2 fuel...
The prospects for liquid hydrogen fueled aircraft Because the world's annual production of petroleum is expected to peak in the 1990 decade, alternative energy sources and fuels must be developed. Due to t... GD Brewer - 《International Journal of Hydrogen Energy》 被引量: 46发表: 1982年 ...
According to JAL, the partnerships will involve"conducting extensive studies"on the feasibility of hydrogen aircraft in Japanese airspace. Current technology means hydrogen-fueled aircraft have a limited range but are feasible for the airline's domestic network. Other crucial aspects of hydrogen flight...
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 ...
