ABSTRACT

An experimental set up has been developed to characterize and measure the thermo-mechanical ablation of a carbon/phenolic composite under the impact of liquid alumina particles. It combines two direct current plasma torches. The present work is focused on temperature measurements around a target located in front of the two plasma flows. The temperature determination method has been developed by LASEP laboratory and is based on the analysis of unresolved groups of UV OH lines. The rotational temperature range is 2000K-8000K. Low temperatures values are compared with the location of melting points of alumina and tungsten rods set in the plasma flow. Surface temperatures of the target are obtained by using optical pyrometry. This work allows to validate a numerical model of the two plasma jet flows impacting the target.
