99--TECHNOLOGY TRANSFER OPPORTUNITY NASA LANGLEYS MULTI-COMPONENT MULTI-POINTINTERFEROMETRIC RAYLEIGH-MIE DOPPLER VELOCIMETER

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. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a new technique for analyzing velocity components, temperature, and density of supersonic and hypersonic aerodynamic and combustion flows. By combining a unique direct view, signal-enhanced interferometric system with Rayleigh scattering detection, the NASA velocimeter can instantaneously measure two orthogonal flow velocity components with high temporal and spatial resolution. By detecting the Doppler shift of Rayleigh effects within the flow, the NASA approachunlike commercial Doppler velocimetry systemsdoes not require particle seeding, enabling a simpler and improved measurement. The developmental and patent pending velocimetry system has been successfully demonstrated in a variety of prototype and advanced working systems in laboratory and wind tunnel facilities. The NASA system is also uniquely capable of characterizing high velocity flames, up to 2400 K, which is very useful in analyzing high-speed combustion in fighter jet engines, scramjet engines, and even potentially gas turbines. The combined features and capabilities of the NASA interferometric Rayleigh scattering velocimeter make it a distinctively versatile and powerful flow analysis tool. To express interest in this opportunity, please respond to contact@example.gov 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.
