Rolls-Royce has entered the final build phase for the world's largest aero-engine technology demonstrator, UltraFan, which provides a suite of technologies to support sustainable air travel. The demonstrator engine, with a fan diameter of 140 inches, is being completed at the company's facility in Derby, UK, prior to its first run on 100% Sustainable Aviation Fuel (SAF) later this year. It offers a 25% fuel efficiency improvement compared with the first generation of Trent engines!
Chris Cholerton, President — Civil Aerospace, Rolls-Royce, said, "Our UltraFan engine technology demonstrator is arriving just as the world is seeking transformative technology to deliver sustainability. We are now in the final build phase and we will perform the first test run on 100% sustainable aviation fuel later this year. The suite of technologies we are testing on the demonstrator will create opportunities to make improvements to our current fleet and provide a new capability for future propulsion systems.
Key engineering features of the engine include:
- Carbon titanium fan blades and a composite casing.
- A new, proven, Advance3 core architecture, combined with our ALECSys lean burn combustion system, to deliver maximum fuel burn efficiency and low emissions.
- Advanced ceramic matrix composite (CMC) components that operate more effectively at high pressures and temperatures.
- A geared design that delivers efficient power for the high-thrust, high bypass ratio engines of the future. The power gearbox has run at 64MW, an aerospace record.
