Characterization of the IXV thermal protection system in high-enthalpy plasma flow
Boekbijdrage - Boekhoofdstuk Conferentiebijdrage
An experimental campaign dedicated to the characterization of Intermediate eXperimental Vehicle thermal protection system is performed in the Plasmatron wind tunnel at the von Karman Institute for Fluid Dynamics.
Emissivity and catalycity properties for representative ceramic specimens are determined under a wide set of operating conditions in order to reproduce the reentry flight trajectory. Intrusive measurements for flow characterization are used together with optical infrared techniques that provide diagnostic of the test articles surface. Experimental data are postprocessed by means of numerical simulations that allow flow enthalpy rebuilding and the characterization the chemical environment for the different conditions investigated.
