UK-based global industrial technology group Rolls-Royce reported on Monday that it had formally started making the biggest aeroengine in the world, the UltraFan. This is intended to be the basis for a new family of engines that would power both single-aisle and widebody airliners and would provide a fuel efficiency improvement of 25% compared with the first generation of the company’s Trent engine family. The assembly of the first module of the new engine had commenced at Rolls-Royce’s DemoWorks in Derby, in the UK. This first, demonstrator, UltraFan, would be finished by the end of this year.
