A fuel tank for use in model airplanes is disclosed, the fuel tank including an angled surface through which the fuel feed line and vent line pass to permit mounting of the fuel tank at the centerline position in profile fuselages, and between closely spaced or behind partly obstructed bulkhea...
Drop-in fuel One of the key benefits of SAF is its compatibility with existing infrastructure. It is a drop-in fuel, meaning it can be blended seamlessly with conventional jet fuel and used in current airplanes. This ease of integration makes Sustainable Aviation Fuel a practi...
The aeronautic industry is facing a new approach on energy generation systems thanksto last decade development on fuel cells technology. Fuel Cells can convert a greatvariety of fuels such as hydrogen, natural gas, methanol, or even the jet fuel used incommercial airplanes into energy without ...
The advantages of fuel-cell auxiliary power in airplanes have been obvious. Fuel cells can generate for an airplane its auxiliary electric power more efficiently than can propulsion-engine powered generators, thus reducing the quantity of fuel that must be carried on a trip. Boeing has now organiz...
used to make hot water and to heat our homes.Methane is not asheavy as gasoline.and it is safer.It does not explode(爆炸)easily.Also,whenmethane burns,very little is left.The air stays lean.There are problems,however.Methane gas takes up a lot of space,Cars and airplanes would need ...
根据One idea is to use old fuels in new ways.和There are problems, however. Methane gas takes up(占用)__a lot of space, Cars and airplanes would need bigger fuel tanks(大容器).__But scientists think they can solve the space problem. They hope that safe, clean methane will be a fuel...
The new study, published today inEnvironmental Research Letters, analyzed around 35,000 flights in both directions between New York and London from 1 December 2019 to 29 February 2020. The team compared the fuel used during these flights with the quickest route that would have been possible at ...
