Rolls-Royce has successfully completed the first tests of its UltraFan technology demonstrator at its facility in Derby, UK. The first tests were conducted using 100% sustainable aviation fuel (SAF).
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 it 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.
In the nearer term, there are options to transfer technologies from the UltraFan development programme to current Trent engines, providing customers with even greater availability, reliability and efficiency.
In the longer term, UltraFan's scalable technology from ~25,000-110,000lb thrust offers the potential to power new narrow-body and wide-body aircraft anticipated in the 2030s.
The tests took place in the company's aero-engine testing facility – Testbed 80. The 100% SAF, derived primarily from waste-based sustainable feedstocks such as used cooking oils, was provided by Air bp.
Testing the demonstrator is the culmination of many years work, which has been supported by the UK Government through the Aerospace Technology Institute (ATI), Innovate UK, the EU's Clean Sky programmes plus LuFo and the State of Brandenburg in Germany.
