Rolls-Royce announces successful run of UltraFan technology demonstrator to maximum power

Rolls-Royce has announced it has successfully run its UltraFan® technology demonstrator to maximum power at its facility in Derby, UK. The initial stage of the test was conducted using 100% Sustainable Aviation Fuel (SAF).

This is an important milestone for the UltraFan demonstrator, which was successfully tested for the first time earlier this year. Since then, the UltraFan team has been gradually increasing the power as part of the rigorous testing regime and the demonstrator has performed in line with our expectations. The results of the test will provide Rolls Royce with valuable learning and data, which their teams will now take away and continue to analyse.

This achievement reinforces confidence in the suite of technologies that has been developed as part of the UltraFan programme. Confirming this capability is a big step towards improving the efficiency of current and future aero-engines as UltraFan delivers a 10% efficiency improvement over our Trent XWB, which is already the world’s most efficient large aero-engine in service. In total that’s a 25% efficiency gain since the launch of the first Trent engine.

UltraFan’s scalable technology from ~25,000-110,000lb thrust also offers the potential to power the new narrowbody and widebody aircraft anticipated in the 2030s.

Tufan Erginbilgic, CEO, Rolls-Royce plc, said:
“Hitting full power with our UltraFan demonstrator sends a strong message that Rolls-Royce is at the cutting-edge of innovation and technology, leading the way in the transition to more efficient and sustainable aviation. This fantastic milestone puts us in a strong position to support the plans of our customers as they develop the next generation of super-efficient aircraft.”

As part of the UltraFan development programme Rolls Royce have also identified a number of technologies that are potentially transferable to current Trent engines, which will provide even greater availability, reliability and efficiency.
