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.
These hydrogen engines burn fuel in the same manner that gasoline engines do. The theoretical maximum power output from a hydrogen engine depends on the air/fuel ratio and fuel injection method used. The stoichiometric air/fuel ratio for hydrogen is 34:1. At this air/fuel ratio, hydrogen will displace 29% of the combustion chamber leaving only ...
The ground test, using a converted Rolls-Royce AE 2100-A regional aircraft engine, used green hydrogen created by wind and tidal power, the British company said on Monday.
The resulting Heinkel-Strahltriebwerk 1 (HeS 1), German for Heinkel Jet Engine 1, was built by hand-picking some of the best machinists in the company, much to the chagrin of the shop-floor supervisors. Hahn, meanwhile, worked on the combustion problem, an area he had some experience in. The engine was extremely simple, made largely of sheet metal.
Rolls-Royce and easyJet, a European-based airline, have successfully tested a hydrogen-powered jet engine, the two companies announced in a press release on Tuesday. The pair say the goal is to ...
The Scimitar engines use technology related to the company's earlier SABRE engine, which is intended for space launch, but here adapted for very long distance, very high speed travel. [citation needed] Normally, as air enters a jet engine, it is compressed by the inlet, and thus heats up. It needs much more power to compress that heated air ...
The Tu-155 was a hybrid, only one of its three Kuznetsov NK-8 engines (they are now called NK-88) was actually powered by hydrogen. [2] The fuel tank was located in the air-blown (or nitrogen) rear compartment. A distinctive feature of the aircraft is that the protrusion of the ventilation system is visible on the tail (near the no. 2 engine).
The intention is to further support the development of their next-generation propulsion, combining jet engines with afterburners fuelled by hydrogen. Its first two subsonic prototypes made successful test flights in 2022. The company states that the third prototype, Destinus 3, is on track to make the hydrogen-powered flight by early 2024. [17 ...
