99--TECHNOLOGY TRANSFER OPPORTUNITY LOW NOISE EXIT GUIDE VANES FOR TURBOFANJET ENGINES

NASA Langley Research Center in Hampton, VA solicits interest from companiesinterested in obtaining license rights to commercialize, manufacture and market thefollowing technology. License rights may be issued on an exclusive or nonexclusive basisand may include specific fields of use. THE TECHNOLOGY: Aircraft jet engine noise remains a major issue for airports, communities near airports,and of course for jet engine designers. NASA Langley and NASA Glenn researchers havedeveloped a novel approach to mitigate the noise generated from exit guide vanes used inhigh-bypass-ratioturbofan engines. Exit guide vanes provide increased thrust and efficiency by controllingthe swirl in the downstream engine flow generated by the turbofan. The interaction ofthis swirling flow with the stationary guide vanes, however, is a significant source ofnoise. Design of the vane shapes and placement have allowed for some reduction in theamount of noise generated. Sound-absorbing linings in the ducting are also used to reducethis turbofan noise as it passes through the engine nacelle. The NASA innovationdescribed here, however, represents a novel design for the construction of the stationaryexit guide vanes to reduce the noise at its source.To express interest in this opportunity, please respond to Sean Sullivan, ResearchTriangle International (RTI), at: NASA Langley Research Center, Strategic RelationshipsOffice (SRSO), 17 West Taylor St., Mail Stop 218, Building 1212, Room 110 Hampton,Virginia, E-mail: contact@example.gov, or phone: +1 (555) 000-0000. Please indicate thedate and title of the FBO notice and include your company and contact information.RTI is responsible for aggregating and acknowledging all responses. These responses areprovided to members of NASA Langleys Innovative Partnerships Office within the SRO forthe purpose of promoting public awareness of our technology products, and conductingpreliminary market research to determine public interest in and potential for futurelicensing opportunities. If direct licensing interest results from this posting, SRO willfollow the formal licensing process of posting in the Federal Register as required. Nofollow-on procurement is expected to result from responses to this Notice.
