Rolls-Royce conducts its first test with the new UltraFan jet engine at the Testbed 80 test facility in Derby, England.
British company Rolls-Royce claims the UltraFan is the quietest and most fuel-efficient aviation engine ever, delivering around 10% better fuel efficiency than the Trent XWB – the world's most efficient aviation engine today.
The first test of UltraFan took place at the Testbed 80 facility in Singin, Derby. In particular, the new engine runs on 100% Sustainable Aviation Fuel (SAV). Rolls-Royce explains that this fuel is mainly made from raw materials derived from waste such as cooking oil.

“UltraFan is the world's largest experimental aviation engine, featuring a host of new technologies that deliver higher fuel efficiency, resulting in lower emissions and greater sustainability. Those technologies can scale, continue to evolve to create engines with thrust from 11,3 tons to more than 45,3 tons for narrow-body or wide-body aircraft," Rolls-Royce explained.
The UltraFan has a huge fan with a diameter of 355,6cm and a relatively small core, which, according to Rolls-Royce, is key to the efficiency of the new engine. The engine delivered 64 MW of power during testing and improved fuel consumption by 25% compared to competitors like Trent.
“UltraFan is designed for the future – it is 100% SAV ready from day one. In addition, we are also actively exploring potential options for hydrogen and hybrid power solutions,” said Rolls-Royce.
The new test is a step towards the aerospace sector's goal of net zero-emissions flight by 2050. The UltraFan project, funded by the UK government, was announced in 2014 and is still growing today.
"This cutting-edge technology will be useful for the transition to a greener future for aviation, while also attracting more investment in the UK aerospace sector, helping to grow the economy," said Kemi Badenoch, UK Trade and Business Secretary.
