99--TECHNOLOGY TRANSFER OPPORTUNITY ACTIVE FLOW EFFECTORS FOR NOISE ANDSEPARATION CONTROL

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. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a novel approach for active jet nozzle flow effectors, or chevrons, based upon shape memory alloy hybrid composite (SMAHC) technology. The concept involves embedding pre-strained SMA actuators on one side of the chevron neutral axis in order to generate a thermal moment and deflect the structure out of plane when heated. The force developed in the host structure during deflection and the aerodynamic loads are used for returning the structure to the retracted position. The NASA chevron design is highly scalable and versatile, and easily affords active and/or autonomous (environmental) control. Prototype chevrons at 1:9 scale have been built and tested, including thermal cycling tests, repeatability tests, and tests with representative flow conditions at NASA Langley. All aspects of the chevron performance were found to be very repeatable, including closed loop performance of the chevron tip to prescribed positions while immersing into and retracting from the flow. 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 the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/. These responses are provided to members of NASA Langleys Office of Strategic Analysis and Business Development (OSACB) for the purpose of promoting public awareness of NASA-developed 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, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
