SILOET 2: Project 5 High Temperature Seals and Oil System

Rolls-Royce and three UK universities are redesigning the hot, high-pressure sections inside jet engines to run at even higher temperatures. Today’s gas turbine engines are limited by how well their internal seals and oil systems can handle extreme heat. Pushing temperatures higher would allow the engine to burn fuel more completely, cutting CO₂ emissions and improving fuel efficiency. It would also extend the life of critical components such as compressor discs and blades, reducing maintenance costs and downtime for airlines. If the project succeeds, the new materials and thermal management designs could be used in future civil aircraft engines, making flying cheaper and less polluting. The same technologies could also be adapted for power-generation gas turbines, helping to reduce emissions from electricity production. For passengers, the most visible change would be lower ticket prices and fewer flight delays caused by engine maintenance—but the real impact would be a quieter, less visible one: a measurable reduction in aviation’s carbon footprint.
