Rolls-Royce reports successful 100% Sustainable Aviation Fuel test flight

Rolls-Royce, working with Boeing and World Energy, has carried out a successful test flight of its 747 Flying Testbed aircraft using 100% Sustainable Aviation Fuel (SAF) on a Trent 1000 engine.

The aircraft flew from Tucson airport in Arizona, passing over New Mexico and Texas, with a Trent 1000 engine running solely on 100% SAF while the remaining three RB211 engines ran on standard jet fuel, arriving back at the airport three hours and 54 minutes later. Initial indications confirm there were no engineering issues, providing further proof of the fuel’s suitability for commercial use.

Rolls-Royce has continued to pioneer the adoption of 100% SAF, and validation of this test adds to those already carried out on its Trent XWB and Pearl engines, both on the ground and in the air.

Last week it confirmed that all of its Trent engines will be compatible with 100% SAF by 2023 and also called for further ambition and collaboration across the aviation sector, and with governments, to enable the transition of long-haul aviation towards net zero ahead of aviation goals set by the UN Race to Zero.

Aircraft are currently only certified to operate on a maximum of 50% SAF blended with conventional jet fuel and Rolls-Royce continues to support efforts to certificate non-blended SAF. This is particularly important to support sustainability in long-distance air travel, which will require the power density of gas turbines for years to come.

The flight was carried out in close collaboration with Boeing, which provided technical support and oversight on aircraft modifications and assurance the aircraft systems would operate as expected with 100% SAF.

World Energy provided the low-carbon fuel for the flight. The need to increase the production of SAF significantly was recognized recently by the US Biden administration with the launch of a Sustainable Aviation Fuel Grand Challenge to produce three billion gallons of the fuel a year by 2030. This will form part of a wider aviation climate action plan to be released in the coming months.

The European Commission has also created a ReFuelEU Aviation proposal that would mandate the incorporation of SAF supplied at EU airports. This would increase to 63% by 2050.

The Rolls-Royce Flying Testbed is used to carry out a variety of engine-related tests that improve efficiency and durability, as well as support the company’s decarbonization strategy.
