Abstract :
Air plasma at approximately 6000 K and atmospheric pressure interacts with an ablative heat shield material. Three physical phenomena are observed: material spallation, evidence of a cooler boundary layer region near the ablator surface in the case of the first material, CBCF, and sodium emission near the ablator surface in the case of the second material, ASTERM.
