Overview of NASA's UEET Program

This paper presents a general overview of NASA's Ultra Efficient Engine Technology (UEET) Program. The program's vision is to develop and hand off revolutionary turbine engine propulsion technologies that will enable future generation vehicles over a wide range of flight speeds. The specific goals include: 1) Perform propulsion technologies to enable increases in system efficiency and, therefore, fuel burn reductions of up to 15% (equivalent reductions in CO2); and 2) Provide combustor technologies (configuration and materials) which will enable reductions in Landing/Take-off (LTO) NOx of 70% relative to 1996 ICAO standards.
