Abstract
Comparative tests using a cold wall heat flux sensor and the TPS basic material SiC were performed in the hypersonic high enthalpy flow of the arc heated facility L2K representing the Martian and air atmospheres. The emission spectroscopy technique was used for the measurement of the emission in the shock layer ahead the stagnation point model. Remarkable difference was noticed in the emission behaviour of these two atmospheres. The cold wall heat flux rate was measured with a Heat-Flux-Microsensor (HFM) based on thermopile technique. Completely different cold wall heat flux rates and surface temperature development on a SiC-probe were measured in air and Martian atmosphere at comparable gas mass flow rate and reservoir pressure levels. The nozzle flow and the flow field around the model was computed using CFD codes including chemical nonequilibrium processes.
