摘要

Laser absorption spectroscopy was applied to the diagnostics of a nonstationary IPG3 airflow to obtain the temporal variations of the flow properties. Consequently, the IPG3 is found to produce a pulsed high-enthalpy flow at 300 Hz, with the averaged pulse duration equal to 33% of a cycle. The time-averaged total specific enthalpy and degree of dissociation in oxygen and nitrogen in this duration are estimated as 23.5 ± 11.4 MJ/kg and 98 and 44%, respectively.
