Rolls-Royce has announced the successful first run of its UltraFan demonstrator at its Derby, UK facility. The UltraFan is a next-generation engine technology designed to deliver improved fuel efficiency and reduced emissions for future aircraft.

The demonstrator ran on 100% Sustainable Aviation Fuel (SAF), marking a significant step in the company's commitment to supporting the aviation industry's net zero ambitions. The UltraFan program aims to provide scalable technology for a range of aircraft, from narrowbody to widebody platforms.

This achievement follows years of research and development, and the data gathered from the demonstrator will inform future engine designs. Rolls-Royce continues to invest in innovation to meet evolving industry requirements and environmental targets.
