NASA’s Advanced Air Transport Technology (AATT) Project explores and develops viable game-changingconcepts, technologies, and tools to improve subsonic fixed-wing commercial transport aircraft energy efficiency,environmental compatibility, and economic impact. Future transports will need to have propulsion systems andairframes that will be more efficient and produce less emissions and noise. Airframes and propulsion systems willbecome more tightly coupled. AATT’s role within NASA aeronautics is provided along with a description ofthe research portfolio and a look ahead to challenges and opportunities.
