Work concluded on the Ultra Efficient Engine Technology (UEET) Project, which began in FY 2000. Among the technical accomplishments, program managers reported success in demonstrating the ability to reduce oxides of nitrogen emissions by 70 percent at landing and take-off to help improve local air quality. The project also reported 10 percent carbon dioxide emission reduction within its subsonic technology portfolio.

Achieving those reductions required the investigation of key technology improvements in the components that make up a jet engine. Improving the efficiency of everything from fan blades to turbine rotors and engine seals to combustor liners contributed to the lowering of emissions.

During the lifetime of the UEET Project, a host of technologies was developed and transferred to the U.S. aeronautics industry, the Department of Defense, Department of Energy, Environmental Protection Agency, and the Federal Aviation Administration.
