Description

NASA Langley Research Center in Hampton, VA solicits interest 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.

THE TECHNOLOGY:

NASA Langley offers you a deployable and stowable mechanical design for filling the cavity behind the leading-edge slat (i.e., slat cove), when it is extended upon landing an aircraft. Aerodynamic flow over an unfilled cavity typically exhibits strongly unsteady behavior that is a source of aeroacoustic noise. Conventional leading-edge slat devices for high lift are a good example of such geometric and flow conditions and are a prominent source of airframe noise. Experimental and computational results have shown that a slat-cove filler device could significantly reduce the noise produced by slat structures. The proposed structural concept is simple and will enable autonomous achievement of the desired deployed shape. The design will facilitate a clean cruise configuration with minimal weight addition to the aircraft. NASA is seeking development partners and potential licensees.

To express interest in this opportunity, please respond to Sean Sullivan, Research Triangle International (RTI), at: NASA Langley Research Center, Strategic Relationships Office (SRSO), 17 West Taylor St., Mail Stop 218, Building 1212, Room 110 Hampton, Virginia, E-mail: Sean.D.Sullivan@NASA.gov, or phone: 757-864-5055. Please indicate the date and title of the FBO notice and include your company and contact information.

RTI is responsible for aggregating and acknowledging all responses. These responses are provided to members of NASA Langley’s Innovative Partnerships Office within the SRO for the purpose of promoting public awareness of our technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, SRO will follow the formal licensing process of posting in the Federal Register as required. No follow-on procurement is expected to result from responses to this Notice.
