Rolls-Royce has successfully run its UltraFan technology demonstrator to maximum power at its facility in Derby.

The test is an important milestone for the UltraFan demonstrator, which was successfully tested for the first time earlier this year.

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 latest test, which was conducted using 100% Sustainable Aviation Fuel (SAF), will provide the company with valuable data.

“This achievement reinforces our confidence in the suite of technologies that has been developed as part of the UltraFan programme,” the company said.

The UltraFan is a big step towards improving the efficiency of current and future aero-engines, with a 10% efficiency improvement over the Trent XWB, which is already the world’s most efficient large aero-engine in service.

In total there has been a 25% efficiency gain since the launch of the first Trent engine.

Tufan Erginbilgic, CEO of Rolls-Royce, 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.”

Simon Burr, group director of engineering, technology and safety, Rolls-Royce, added: “We estimate that to reach Net Zero flying by 2050, a combination of highly-efficient, latest-generation gas turbines such as UltraFan operating on 100% SAF are likely to contribute around 80% of the total solution, which is why today’s announcement is such an important milestone for Rolls-Royce and the wider industry.”
