A Laser-Based Diagnostic Suite for Hypersonic Test Facilities, Phase II

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 utilize diode laser spectroscopy to determine several critical parameters including gas temperature, velocity, and composition. Moreover, by using both multiple lines-of-sight and multiple wavelengths, the analyzer will also provide a measure of the spatial distribution of these important gas parameters in an engine test facility. The SBIR instrument will be the first system capable of providing real-time, rapid quantification of these important combustion parameters in NASA's hypersonic test facilities. Such quantification is essential to the development of improved reactive CFD models and subsequent hypersonic propulsion systems for future aerospace vehicles. More »
