SILOET Project 7 - Component Technologies

Aerospace engineers are testing new seals, repair techniques, and oil systems inside jet engines to cut fuel burn by making the engines run hotter and more efficiently. This matters because jet engines waste a significant amount of fuel through leakage, friction, and heat loss in their internal air and oil systems. The project tackles three specific components that contribute to this waste: compressor blisks (the spinning discs that compress air), advanced seals (which prevent high-pressure air from leaking where it shouldn’t), and the oil system (which lubricates and cools moving parts). The blisk work focuses on repair technologies to extend part life and reduce costs. If successful, these component technologies could lower fuel consumption for commercial and military aircraft. That means lower operating costs for airlines and reduced carbon emissions per flight. The improvements are invisible to passengers—they will never see a seal or a blisk—but they quietly make air travel cheaper and less polluting. The project is applied engineering, not fundamental science; its goal is a direct, measurable reduction in fuel burn through hardware that can be demonstrated in rig tests and engine demonstrations.
