Technology Transfer Opportunity Supersonic Laminar Flow Control LarTops311 Description NASAs Technology Transfer Program 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 NASAs Langley Research Center has developed a technology that is projected to extend the laminar flow area over supersonic flight configurations by delaying the transition of boundary layer flow from laminar to turbulent state This controls laminar flow over airframe components including wings empennage engine nacelles and the nose region of an aircraft fuselage It can be used in combination with many of the existing techniques for passive and active laminar flow control but is particularly wellsuited for a supersonic natural laminar flow design by virtue of avoiding the space weight system complexity and maintenance penalties associated with suction based laminar flow control This technique injects precisely defined stationary transient growth disturbances into the free air slipstream over a wing that develop into streamwise elongated quotstreaksquot These streaks are created with an alternating pattern of low and high streamwise velocity in the boundary layer flow adjacent to the aerodynamic surface of interest Judicious selection of streak wavelength amplitude and profile allows the firstmode instability waves responsible for transition via oblique mode breakdown to be damped while the remaining uncontrolled waves are kept below an amplification threshold A similar control concept is also applicable to second mode transition at hypersonic Mach numbers To express interest in this opportunity please submit a license application through NASAs Automated Technology Licensing Application System ATLAS by visiting https technologynasagov patent LARTOPS31 NATIONAL AERONAUTICS AND SPACE ADMINISTRATION Contracting Office Address HOUSTON TX 77058 HOUSTON TX 77058 USABR Primary Point of Contact Kathryn Taylor kathryntaylornasagov Phone Number 2814832361BR Secondary Point of Contact Karen Dailey karenjdaileynasagov Phone Number 2814833445 agencypatentlicensingmailnasagov Tender Notice International Competitive Bidding T2PLaRC00114 United States of America GT90150106
