TECHNOLOGY TRANSFER OPPORTUNITY: Novel turboelectric commercial aircraft Design with significantly reduced in fuel burn and emissions: LAR-18858-1

Synopsis: NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a novel aircraft design that can carry 150 passengers over a range of 3,500 nautical miles. Key features include a turboelectric propulsion system, twin underwing turbofans, and a rear fuselage electrically driven boundary layer ingesting fan. The design is developed for single-aisle class aircraft (the largest commercial transport class in the world) to significantly reduce fuel burn compared to current aircraft. Benefits compared to traditional designs include more efficient fuel usage, lower emissions, and reduced weight penalty from additional components. The novel propulsion architecture uses hydrocarbon fuels to power two underwing turbofans that also contain generators. The underwing turbofans burn traditional jet fuel and provide thrust throughout the mission. The generators on the turbofans extract power from the fan shaft and send the power to a rear fuselage electric motor operating at a constant 3,500 hp. The motor then turns an annular fan that operates at a fan pressure ratio of 1.25. The rear fuselage propulsor is extremely efficient, allowing the turbofans to be decreased in size. This can reduce weight penalties associated with the additional electrical components and rear fan. NASA is seeking to license this technology commercially in the United States. US Patent pending. To express interest in this opportunity, please respond to [email protected] with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide how you foresee using the technology along with a brief background of your company. Additionally, please identify any non-US interests/subsidiaries in your company as well.
