99--TECHNOLOGY TRANSFER OPPORTUNITY AUTONOMOUS SLAT COVE FILLER DEVICEREDUCTION OF AEROACOUSTIC NOISE ASSOCIATED WITH THE LEADING EDGE OF AIRCRAFT WINGS

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: NASA Langley offers you a deployable and stowable mechanical design for filling thecavity behind the leading-edge slat (i.e., slat cove), when it is extended upon landingan aircraft. Aerodynamic flow over an unfilled cavity typically exhibits stronglyunsteady behavior that is a source of aeroacoustic noise. Conventional leading-edge slatdevices for high lift are a good example of such geometric and flow conditions and are aprominent source of airframe noise. Experimental and computational results have shownthat a slat-cove filler device could significantly reduce the noise produced by slatstructures. The proposed structural concept is simple and will enable autonomousachievement of the desired deployed shape. The design will facilitate a clean cruiseconfiguration with minimal weight addition to the aircraft. NASA is seeking developmentpartners and potential licensees. 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: [email protected], or phone: 757-864-5055. 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.
