Nasa’s Ultra-efficient Engine Technology (ueet) Program/aeropropulsion Technology Leadership for the 21 Century

One of NASA's four main product lines is developing and transferring to U. S. industry enabling technologies required for next generation aerospace vehicles as part of the Aerospace Technology Enterprise. This paper overviews the Ultra Efficient Engine Technology (UEET) Program, NASA's focused aerospace propulsion technology program. The UEET Program emphasizes technology development in six selected areas --low emissions combustion, highly loaded turbomachinery, high temperature materials and structures, intelligent propulsion controls, propulsion-airframe integration, and integrated component technology demonstrations. In addition, systems studies provide a system integration function for the UEET program to ensure that proper investments in technology are made. The paper overviews the content of each element of this UEET Program as well as the approach being followed to program management. The paper will also describe possible collaboration effects with other government programs (NASA, DOD).
