Flight-Ready TDLAS Combustion Sensor for the HIFiRE 2 Hypersonic Research Program

Abstract : Advanced air-breathing engine development requires new combustion diagnostics. The new sensors must not intrude into the engine and the sensing components must endure the thermal and vibrational environment near a scramjet combustor. The sensor should also be suitable as a diagnostic in realistic scramjet test situations, including in flight in sounding-rocket test vehicles. The development of a laser sensor meeting these requirements for the HIFiRE 2 hypersonic research program is described in this report.
