SUGAR team on Task 1 of the Phase II effort The team consisted of Boeing Research and. Technology Boeing Commercial Airplanes General Electric and Georgia Tech. Using a quantitative workshop process the following technologies appropriate to aircraft. operational in the N 4 2040 timeframe were identified Liquefied Natural Gas LNG. Hydrogen fuel cell hybrids battery electric hybrids Low Energy Nuclear LENR boundary layer. ingestion propulsion BLI unducted fans and advanced propellers and combinations. Technology development plans were developed, The team generated a series of configurations with different combinations of some of these. technologies The higher heating value of LNG reduces the weight of fuel burned but because. of heavier aircraft systems more energy is used for a given flight LNG fueled aircraft have the. potential for significant emissions advantages and LNG enhances the integration of fuel cells. into the aircraft propulsion and power system, An unducted fan increases propulsive efficiency and reduces fuel burn Adding a fuel cell and. electric motor into the propulsion system also leads to improvements in emissions and fuel. burn An aft fuselage boundary layer propulsor also resulted in a fuel burn benefit. NASA Contract NNL08AA16B NNL11AA00T Subsonic Ultra Green Aircraft Research Phase II. N 4 Advanced Concept Development, Part of the mission of Boeing Research Technology as the company s advanced central. research and technology organization is to help create the long term future of aerospace by. identifying and maturing new technologies, However while Boeing is interested in developing environmentally progressive vehicles it. would be premature to conclude that any of the concepts studied under this contract will. replace any of Boeing s commercial products, This is an advanced concept and technology study that examines a wide variety of alternative.
fuel and energy technologies and is not an offer commitment or promise on the performance. or capabilities of any future Boeing product, NASA Contract NNL08AA16B NNL11AA00T Subsonic Ultra Green Aircraft Research Phase II.
