  1. Low-NOx Fuel-Injector for Aircraft-Engine Combustors Small Business Innovation Research CFD Research Corporation Huntsville, AL INNOVATION Piloted airblast lean-direct fuel-injector that utilizes a bifurcated flow pattern for low emissions • ACCOMPLISHMENTS • Emission results were obtained with single-injector tests • A 60-65% reduction of NOx levels compared to 1996 International Civil Aviation Organization’s (ICAO) defined landing-takeoff cycle (LTO) standards was obtained • Achieved a lean-blowout equivalence-ratio of 0.08 • Demonstrated reliable ignition and altitude relight Cross-Section of Prototype Fuel Injector • COMMERCIALIZATION • Approximately $1.5M of funding received from three aircraft-engine manufacturers, and additional funding to be received in the future • Obtained U.S. Patent No. 6,272,840 • Potential for obtaining patent license agreements and royalties • GOVERNMENT/SCIENCE APPLICATIONS • Fuel injector further developed under NASA Advanced Subsonic Technology (AST) and Ultra Efficient Engine Technology (UEET) programs • U.S. Navy has shown interest in marine application 1994 Phase II, NAS3-27746, 2/02 NASA Contact – Paul Penko Company Contact – Clifford Smith Glenn Research Center Aeronautics 3-082
