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.
Program successes included the concept design of a Mach 2.5 aircraft capable of flying at 30,000 meters, and successful conversion of an existing turbojet engine to run on liquid hydrogen, as well as 25+ hours of testing on a customized LH2 engine design. Techniques for handling LH2 on the ground, including making the fuel, transporting and ...
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).
As part of its goal to have zero-emission aircraft enter service by 2035, Airbus has announced the development of a hydrogen fuel-cell engine designed to for airplanes.
Hydrogen fuel could save £150,000–£300,000 annually over fossil fuel, maintenance costs should fall by 50% for the propulsion system, and 15% for the whole aircraft. [5] Rolls-Royce plc left the consortium, while engineering company Ricardo plc will integrate the two 250 kW (340 hp) fuel cells and Innovatus Technologies the composite ...
The key technology shift was switching from solar power to liquid hydrogen power. Global Observer – The Los Angeles Times reported first flight of Global Observer in the Mojave Desert in January, 2011. [7] The aircraft was powered by hydrogen. It appears to have 4 motors with twin-bladed props, a 175-foot (53 m) wingspan, 65,000-foot (20,000 ...
