A Two-Line Absorption Instrument for Scramjet Temperature and Water Vapor Concentration Measurement in Hypulse

By: Nasa, National Aeronautics and Space Adm

A three beam water vapor sensor system has been modified to provide for near simultaneous temperature measurement. The system employs a tunable diode laser to scan spectral line of water vapor. The application to measurements in a scramjet combustor environment of a shock tunnel facility is discussed. This report presents and discusses die initial calibration of the measurement system.
