Abstract

To allow validation of the numerical codes applied to simulate flow field and radiation properties of the EXOMARS COMARS+ flight data from Schiaparelli capsule descent phase, further Martian atmosphere experiments in DLR's arc heated facility L2K with dedicated diagnostics are being performed. Two test case flow conditions with different enthalpies have been identified for Martian atmosphere to measure thermochemical and radiation properties in the free stream and behind a shock layer of a scaled model of the Schiaparelli capsule. The COMARS+ broadband radiometer is used to measure the radiation properties of both the free stream and the shock region. For characterization of the thermochemical properties of free stream and shock region non-intrusive spectroscopic measurement techniques as Fourier Transformed InfraRed spectroscopy (FTIR) and UV-VIS Emission Spectroscopy (ES), Laser Induced Fluorescence spectroscopy (LIF), and Diode Laser Absorption Spectroscopy (DLAS) are used. Additionally profiles of Pitot pressure and heat flux have been measured to verify homogeneity of the free stream at the model location.
