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.
The main factors affecting gainable water are the hydrogen content of the fuel and humidity. The necessary exhaust gas coolers for this method had repeated problems with corrosion in the early years. The first trials on the DELAG-Zeppelin LZ 13 Hansa (1912–1916) were conducted by Wilhelm Maybach. The trials were not satisfactory, resulting in ...
Some development of technology for hydrogen-powered aircraft started after the millennium and gained track since about 2020, but as of 2022 was still far away from outright aircraft product development. Hydrogen fuel cells do not produce CO 2 or other emissions (besides water). However, hydrogen combustion does produce NO x emissions.
Aircraft fuel tanks are a major component of aircraft fuel systems. They can be classified into internal or external fuel tanks and can be further classified by method of construction or intended use. Safety aspects of aircraft fuel tanks were examined during the investigation of the 1996 TWA Flight 800 in-flight explosion accident.
The latest collaboration will bring rapidly-increasing hydrogen capability to Cummins (CMI) in order to expand its fuel cell and hydrogen-processing technology capabilities.
Bowser also describes a fuel tanker used to deliver fuel to aircraft at airports or airfields. [2] The term also describes refuelling boats that supply seaplanes, army fuel tankers used for combat resupply, and vehicles that fill heavy construction equipment such as hydraulic excavators and bulldozers. Even aircraft have been described as ...
Hygate estimates that if all usable UK sewage waste was put into making aviation fuel, it would still only meet 5% of the UK’s demand for jet fuel. Therefore, it would have to be used alongside ...
Usually the fuel in the drop tanks is consumed first, and only when all the fuel in the drop tanks has been used, the fuel selector is switched to the airplane's internal tanks. Some modern combat aircraft use conformal fuel tanks (CFTs) instead of or in addition to conventional external fuel tanks. CFTs produce less drag and do not take up ...
