Rolls-Royce are underway with building the world’s largest aero engine – Ultrafan. They claim it will re-define sustainable air travel for decades.
The actual fan alone has a diameter of 3.5 metres. It has carbon titanium fan blades and a composite casing that can reduce weight by 680kg per aircraft. But it is the components and gearing that will help the efficiency demanded by the future of air travel.
Advanced ceramic matrix composite (CMC) components are used that operate more efficiently in high pressure turbine temperatures. A geared design delivers efficient power for the high-thrust, high bypass engines of the future.
The culmination of these features is set to provide a 25% fuel efficiency compared with the first generation of Trent Engine. See the full article below….
