99--TECHNOLOGY TRANSFER OPPORTUNITY MICRO-LIDAR FOR FLOW VELOCIMETRY WITHOUTPARTICLE-SEEDED FLOWS

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 miniaturized light detection and ranging (LIDAR) velocimetry sensor to analyze high velocity and boundary layer flows in real-world conditions. Using Rayleigh scattering, as opposed to the more common particle scattering, the patent pending NASA sensors provide multiple flow parameters without the need for particle- seeded flows. The compact fiber optic sensor design can be embedded directly in a test surface and allows for a variety of near-surface measurement formats enabling real-time three-component flow velocity mapping, composition, gas density, and temperature data. The versatility of the NASA Micro-LIDAR sensor platform offers broad utility in advanced aerodynamic and fluid dynamic applications requiring boundary layer, unseeded flow measurements. The NASA Micro-LIDAR sensor combines high laser intensities over a small flow volume near a surface and good signal collection efficiencies to enable Rayleigh scattering measurements, which eliminates the need for particle-seeded flows. In addition to unseeded flow velocimetry, the NASA sensor format can be reconfigured as spectroscopy, induced fluorescence, and differential measurement devices to provide flow composition, gas density, temperature, and pressure data. The multi-parameter miniaturized NASA sensor format provides for an unobtrusive in-flight method to determine laminar versus turbulent flow in the boundary layer. When combined with surface actuators in a closed loop control system, the NASA sensor creates the potential for active boundary layer control. The combination of real-time measurements, embedded sensor arrays, and unseeded flow capability embodied in the NASA sensor platform provides industry a powerful real-world flow analyses tool.
