ROLLS-ROYCE SUCCESSFULLY TESTS ULTRAFAN TECHNOLOGY DEMONSTRATOR
The first tests were conducted using 100% Sustainable Aviation Fuel (SAF) at the Rolls-Royce facility in Derby, UK.
Rolls-Royce announced it has successfully completed the first tests of its UltraFan technology demonstrator. This is a historic moment for Rolls-Royce – it’s the first time in 54 years the aero-engine manufacturer has tested a brand-new engine architecture and is proof of what can be achieved when industry and Governments work together.
Confirming the capability of the suite of technologies incorporated in the demonstrator is a big step towards improving the efficiency of current and future aero-engines. UltraFan delivers a 10% efficiency improvement over the Trent XWB, which is already the world’s most efficient large aero engine in service.
In the nearer term, there are options to transfer technologies from the UltraFan development programme to current Trent engines, providing our customers with even greater availability, reliability and efficiency.
In the longer term, UltraFan’s scalable technology from ~25,000-110,000lb thrust offers the potential to power new narrowbody and widebody aircraft anticipated in the 2030s.
The tests took place in the world’s largest and smartest indoor aero-engine testing facility – Testbed 80. The 100% SAF, derived primarily from waste-based sustainable feedstocks such as used cooking oils, was provided by Air bp.
UltraFan has been a decade in the making, with the concept unveiled publicly in 2014. It is a fundamentally different design architecture to that within the approximately 4,200 Rolls-Royce Civil large engines currently in service, as it incorporates a geared design that no other industry player has produced at this size before.
Key engineering features of the demonstrator include:
- A new, proven, Advance3 core architecture, combined with our ALECSys lean burn combustion system, delivers maximum fuel burn efficiency and low emissions
- Carbon titanium fan blades and a composite casing
- 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.
