Rolls-Royce has started manufacture of the world’s largest fan blades, for its UltraFan demonstrator engine that will set new standards in efficiency and sustainability.

As a set the composite blades have a 140 inch diameter, which is almost the size of a current narrowbody fuselage, and are being made at the company’s technology hub in Bristol, U.K. The milestone also marks the official start of production of parts for the demonstrator.

UltraFan will set new standards in efficiency and sustainability, offering a 25 per cent fuel reduction compared to the first generation of Trent engine, and deliver the same percentage reduction in emissions.

Part of that efficiency improvement comes from UltraFan’s composite fan blades and fan case, which reduce weight on a twin-engine aircraft by 700kg, the equivalent of seven people travelling “weight free”.
