Dynamic oxidation of TPS materials for reusable space vehicles using arc-heated wind tunnel

In order to investigate of the oxidation behaviors of Thermal Protection System (TPS) for space planes, the development of the arc-heated wind tunnel was conducted. ZrN, TiN, TiCN coatings were applied on the Zr cathode using ion plating method and Cu-Cr alloy was coated on the Cu anode expecting for reducing of the electrodes erosion. Pre-heating of the cathode with laser was also effective for preventing the erosion. Dynamic oxidation of the TPS were conducted using laser driven plasma wind tunnel.
