Abstract
An arc heated wind tunnel used for sample heating test of thermal protective materials for high speed space vehicle, probe and capsule. This study is series of attempt of ablation phenomena related the plasma characteristics to the thermally decomposed gas, the chemical composition and material structure after an arc heating test. Sample heating supersonic test during versin graphite and graphite penetrated by silicone oil target in an arcjet flow is experimentally studied on measurements of radiation temperature and internal temperature in the ablation materials.
