Just when you thought the apex of innovation had been reached, Rolls-Royce challenges the notion and takes a huge leap into the future. After fifty long years of diligent research, design tweaks, and rigorous testing, the company has unveiled an absolutely novel engine design, the UltraFan. This cutting-edge marvel operates on Sustainable Aviation Fuel (SAF), promising enhanced fuel efficiency – about 10% more than Rolls-Royce’s current crown jewel, the Trent XWB.
