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 [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.
