4.5 Ultra Efficient Engine Technology Program
NASA's Ultra Efficient Engine Technology Program will improve air quality around airports. NASA's role in civil aeronautics is to develop high risk, high payoff technologies to meet critical national aviation challenges. Currently, a high priority national challenge is to ensure U.S. leadership in aviation in the face of growing air traffic volume, new safety requirements, and increasingly stringent noise and emissions standards. The primary objective of the new Ultra-Efficient Engine Technology Program is to address two of the most critical propulsion issues: performance/efficiency and reduced emissions for a wide range of applications, both civil and military. High performance, low emissions engine systems will lead to significant improvements in local air quality and have a minimum contribution to ozone depletion, which will result in an overall reduction in aviation's contribution to global warming. The UEET program will address local air quality concerns by developing technologies to reduce nitrogen oxide (NOx) emissions by 70 percent at landing and take-off (LTO) conditions, from 1996 International Civil Aviation Organization (ICAO) standards. In addition, the UEET program will address potential ozone depletion concerns by demonstrating combustor technologies that prevent any discernible aircraft impact on the ozone layer during cruise operation (up to a 90 percent reduction). This program enables the U.S. to be competitive in developing very low emissions propulsion systems. Additionally, the UEET program will address the impact of projected aviation growth on the climate by providing critical propulsion technologies for a dramatic increase in efficiency. This increased efficiency will enable reductions of carbon dioxide (CO2) emissions based on an overall fuel savings goal of about 15 percent for large subsonic transport or as much as 8 percent for supersonic and/or small aircraft. Fuel savings represent significant cost benefits to the traveling public.
