The hydrogen-powered Tu-155 prototype made its first flight on 15 April 1988.. A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor.
HY4 is a four seat hydrogen fuel cell powered aircraft. It made its maiden flight on 29 September 2016 from Stuttgart Airport, powered by gaseous hydrogen.It was designed by DLR Institute of Engineering Thermodynamics of the German Aerospace Center, [2] [3] [4] based on the Taurus G4, manufactured by Pipistrel.
Jet fuel is a gas turbine fuel used in propeller and jet fixed-wing aircraft and helicopters. It has a low viscosity at low temperature, has limited ranges of density and calorific value , burns cleanly, and remains chemically stable when heated to high temperature.
An electric aircraft runs on electric motors with electricity coming from fuel cells, solar cells, ultracapacitors, power beaming, [42] or batteries. Currently, flying electric aircraft are mostly experimental prototypes, including manned and unmanned aerial vehicles, but there are some production models on the market. [43]
In some aircraft, the shut-off function is a different valve located after the fuel selector valve. Typically, after the selector valve—situated at a low point in the fuel run—there is a gascolator — a fuel filter that can be opened on the ground and drained of fuel impurities denser than petroleum, mainly water and sediment. Other ...
Fuel cells are very useful as power sources in remote locations, such as spacecraft, remote weather stations, large parks, communications centers, rural locations including research stations, and in certain military applications. A fuel cell system running on hydrogen can be compact and lightweight, and have no major moving parts.
Australian Federal Police said in a statement that “officers arrested a man after he allegedly ran naked through the aircraft mid-flight and knocked a crew member to the floor.”
The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons ...
