TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
In this SBIR effort, Los Gatos Research (LGR) proposes to develop a suite of laser-based diagnostics for the study of reactive and non-reactive hypersonic flows. These sensors will include both in situ and line-of-sight measurements of several critical parameters including gas temperature, velocity, and composition. Both established near-infrared and emerging mid-infrared laser sources will be utilized to make highly-accurate measurements via tunable diode laser absorption spectrometry. The SBIR instrument will be the first system capable of providing real-time, rapid quantification of these important combustion parameters in NASA's hypersonic wind tunnels. Such quantification is essential to the development of improved reactive CFD models and subsequent hypersonic propulsion systems for future aerospace vehicles.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
In order to develop next-generation hypersonic vehicles, NASA researchers rely heavily on ground test facilities and complex numerical simulations. These models require a series of assumptions regarding important chemical species and the nature of turbulent flow to become tractable. Due to the complexity of these models and their parameters sensitivities, current CFD calculations lack sufficient predictive capabilities. In order to validate and refine these models, it is necessary to equip ground test engines with diagnostics that are capable of accurately measuring the gas temperature, gas velocity, and concentrations of key chemical species at several points within the turbulent flow field. By comparing the diagnostic results directly to numerical simulations, the modeling of compressible, turbulent flow can be greatly improved, enabling the production of next-generation propulsion systems

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Besides its application to NASA, a laser-based gas analyzer also has significant commercial application. Through a series of strategic partnerships, LGR is developing a suite of analytical instrumentation to measure trace gases for industrial process control monitoring and petrochemical applications. The proposed work is essential in making these instruments more compact, rugged, and cost competitive, and will thus enlarge the potential market size significantly.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
