Rolls-Royce Conducts Successful Test Of UltraFan Technology Demonstrator Using SAF

Rolls Royce has completed a successful test of its new UltraFan technology demonstrator using 100 per cent sustainable aviation fuel, demonstrating a new architecture for engines.

Rolls-Royce today announced that it has successfully completed the first tests of its UltraFan technology demonstrator at its facility in Derby, UK. The first tests were conducted using 100 per cent Sustainable Aviation Fuel (SAF). This is a historic moment for Rolls-Royce - it is the first time in 54 years that 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 per cent 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.

The use of sustainable aviation fuel is increasing across the world among various airlines. Beginning the use of SAF, Vistara became the first Indian airline to operate a commercial, domestic flight with environment-friendly fuel. The full-service carrier used a brand-new Boeing 787-9 Dreamliner aircraft. The aircraft completed its journey between Delhi's Indira Gandhi International Airport and Mumbai's Chhatrapati Shivaji Maharaj International Airport. The Boeing aircraft used a blend of 17 percent SAF with 83 percent conventional fuel.

Also, an Air Asia flight today operated on  SAF blend.  "Today, I received crew and passengers who took the first commercial passenger flight from Pune to Delhi powered by indigenously produced sustainable aviation fuel (SAF). It's the beginning of a new chapter in sustainable aviation fuel (SAF). Today we have started with 1% blending of SAF in one flight, which will be taken to 1% in all flights by mid-2025," said Union Petroleum Minister Hardeep Singh Puri, on receiving the crew and passengers of the flight.
