This is a historic moment for Rolls-Royce – it’s the first time in 54 years the aero-engine manufacturer has tested a brand-new engine architecture and is proof of what can be achieved when industry and Governments work together.

Confirming the capability of the suite of technologies incorporated in the demonstrator is a big step towards improving the efficiency of current and future aero-engines. UltraFan delivers a 10% efficiency improvement over the Trent XWB, which is already the world’s most efficient large aero engine in service.
