炭化珪素の繰り返しアーク加熱実験

Abstract

Arc heated wind tunnel is usually used for hypersonic and supersonic heating test of thermal protective material under the planetary entry. Then，the reentry in earth， a capsule or a reusable rocket is exposed to the atmosphere a b ow shock wave takes place tip on body detached from its nose. The study is to investigate that repeated arc heated testing affect to crystal structure and high temperaturem echanical property of silicon carbide (SiC)，Shore hardness，crystal structure and to obtain temperatures from black body radiation temperature.
