Diode Laser Absorption Spectroscopy Measurements in a Gaseous Hydrogen / Oxygen Rocket

Abstract: Tunable diode laser absorption spectroscopy (TDLAS) has been used to make pathintegrated temperature measurements in a gaseous oxygen / gaseous hydrogen uni-element rocket chamber with hot background flow. Four mixture conditions were studied at a nominal chamber pressure of 100 psia. Near infrared diode lasers were utilized to target rovibrational transitions of water vapor combustion product. Both direct absorption spectroscopy and wavelength modulation spectroscopy with second harmonic normalized by first h… Show more
