Rolls-Royce has officially started building the world’s largest aero-engine, UltraFan®, which will help redefine sustainable air travel for decades to come.
Work on the first module is underway at our dedicated DemoWorks facility in Derby, UK, and the demonstrator engine, which has a fan diameter of 140 inches, will be completed by the end of the year.
The engine is the basis for a potential new family of UltraFan engines able to power both narrowbody and widebody aircraft and deliver a 25% fuel efficiency improvement compared with the first generation of Trent engine.
