Abstract

Flow Control using electromagnetic fields is one of the options to reduce aerothermal loads to the spacecraft structures in ionized high enthalpy flows. First computational studies made immediately evident the necessity of well designed and cleanly performed experiments. Therefore in the frame of ESA collaborative study on the electrodynamic-heatshield concept an experimental study has been carried out in the arc heated facility L2K. The results of the experiments should also lead to a better understanding of physical phenomena and providing reliable data for the validation of numerical codes. A cylinder with a flat upstream end with integrated magnet coils were investigated in a hypersonic high-enthalpy ionized-argon flow field
