Rolls-Royce to test 100% Sustainable Aviation Fuel in next-generation engine demonstrator
The Rolls-Royce Trent engine, housing ALECSys technology, that will be used for the Sustainable Aviation Fuel tests Ground tests with 100% Sustainable Aviation Fuel (SAF) to demonstrate Rolls-Royce engines can unlock SAF’s potential to reduce emissions As part of its ongoing decarbonisation strategy, Rolls-Royce is to use 100% sustainable aviation fuel for the first time in engine ground tests on next-generation engine technology.
The tests will aim to confirm that unblended SAF makes a significant contribution to improving the environmental performance of gas turbine engines.
The SAF being used in the tests was produced by low-carbon fuel specialist World Energy in Paramount, California, sourced by Shell Aviation and delivered by SkyNRG. This unblended fuel has the potential to significantly reduce net CO2 lifecycle emissions by more than 75 per cent compared to conventional jet fuel, with the possibility of further reductions in years to come.
These tests aim to demonstrate that our current engines can operate with 100% SAF as a full “drop-in” option, laying the groundwork for moving such fuels towards certification. At present, SAF is certified for blends of up to 50% with conventional jet fuel and can be used on all current Rolls-Royce engines.
Starting in the coming weeks in Derby, UK, the ground tests will involve a Trent engine which also incorporates ALECSys (Advanced Low Emissions Combustion System) lean-burn technology.
ALECSys is part of the UltraFan® next generation engine demonstrator programme, which offers a 25% fuel saving over the first generation of Trent engines.
Paul Stein, Rolls-Royce Chief Technology Officer, said: “Aviation is a tremendous force for good, keeping the world connected, but we have to do that sustainably. These tests aim to show that we can deliver real emissions reductions. If SAF production can be scaled up – and aviation needs 500 million tonnes a year by 2050 – we can make a huge contribution for our planet.”
Gene Gebolys, Chief Executive Officer and founder, World Energy, said: “World Energy exists to empower leaders to innovate by providing the world’s most advanced low carbon fuels. Rolls-Royce is putting their technological prowess to work to understand how to maximise their potential in engines and we are proud to support them.”
Theye Veen, Managing Director, SkyNRG, added: “This programme is a great example of what can be achieved when companies from across the aviation value chain that share an ambition of reducing emissions work together. As a pioneer in SAF, SkyNRG encourages innovative tests like this run by Rolls-Royce.”
In addition to supplying the SAF with SkyNRG, Shell Aviation is also providing Rolls-Royce with AeroShell lubricants for the ALECSys engine test programme.
Anna Mascolo, President, Shell Aviation, commented: “For over 100 years, Rolls-Royce and Shell have worked together to drive aviation’s progress. This collaboration brings us one step closer to decarbonising Aviation. As well as the SAF, Shell Aviation will provide offsets using nature-based solutions to make the test net zero emissions, reinforcing how multiple measures are essential if aviation is to achieve net zero carbon dioxide emissions.”
The ALECSys programme is supported by the European Union via Clean Sky and in the UK by the Aerospace Technology Institute and Innovate UK; the 100% SAF testing programme is additionally supported by ATI, iUK and Gulf Aviation.
Rolls-Royce Launches First-time Immersive Virtual Reality Training For Business Aviation Customers
Even during the COVID-19 pandemic, Rolls-Royce continues to ensure world-class support for our global customer base. As part of our IntelligentEngine vision we are further expanding the use of immersive Virtual Reality technology for customer training.
The latest addition to the remote training programme is an instructor-led distance learning course, providing a comprehensive overview of the construction, design and operation of the Rolls-Royce BR725 engine that powers Gulfstream’s current flagship G650 business aircraft family. After completion of this comprehensive two-day training course, participants will be able to service the engine and undertake non-routine maintenance.
Andy Robinson, SVP Customers and Services – Business Aviation, Rolls-Royce, said: “Rolls-Royce has been the leading engine supplier for business aircraft for more than two decades thanks to our continued commitment to the highest levels of service support. We are tremendously proud to have been voted number one in the latest Engine Product Support Services Survey of Aviation International News (AIN) by our operators.
Digitalisation plays a vital role in in bringing our IntelligentEngine vision to life; we use it to design, test and maintain our engines. This new immersive live Virtual Training tool is nothing short of a game-changer – it makes us the leader in technical training and allows customers to participate in the new training, wherever they are in the world. They just need an internet connection, and the required VR equipment, which will be shipped directly to their door,” Andy added.
Lee Bradshaw, Director of Technical Operations, Cox Aviation, said: “The new Virtual Reality maintenance course is a great example of the innovative thinking that is needed to meet the challenges of our ever-changing world. This programme allows each student to immerse themselves in an augmented environment full of realistic images, interactive functions and auditory feedback to delve deeper into the engine like never before. The course complements the industry-leading service already provided by Rolls-Royce and is another reminder of why this company is pioneering the way in creative solutions for the future.”
While not intended to completely replace practical training, Rolls-Royce see the value Virtual Reality adds for customers, such as higher flexibility and the elimination of the need to ship a full size training engine. The user finds themself as part of two realistic scenarios – the engine installed on the aircraft in a virtual hangar and the BR725 engine alone, just like it would be in our in-person training courses. The immersive environment allows them not only to watch the process steps to get familiar with the respective task, but to interact with the engine and the tools, and actually accomplish the task under the constant supervision of the instructor.
