A review is given of the NASA's ongoing and planned research and technology programs leading to advanced air breathing propulsion systems of the next century. The primary focus is on efforts being performed or sponsored by NASA-Lewis, with emphasis on civil, subsonic, and supersonic transportation systems which should begin to enter service within 10 to 20 years. Subsonic transport propulsion program elements, including ducted UltraHigh Bypass (UHB) engines and high efficiency cores are discussed in terms of goals, technical issues and problems, approaches and plans. Similarly, The Supersonic Cruise Propulsion Program is reviewed via discussion of near term and far term goals; barrier issues such as NOx and noise reduction and the consequent Phase 1 (near term) research plans are described; and finally, emerging technologies such as the supersonic through-flow fan are considered for their potential long term impact.
