| Outline of Final Research Achievements |
In this research, we make clear intense radiation around Si-based ultrahigh-temperature heat-resistant materials in high-enthalpy flows by using an advanced spatial-temporal emission spectroscopic measurements. Main results of this research are as follows. (1) We obtained intense radiation around Si-based ultrahigh-temperature heat-resistant materials in high-enthalpy flows by using several kinds of narrow band-pass filters and general-purpose video cameras, and we estimated temperature distributions of the materials in the high-enthalpy flows by means of the radiation intensity ratio. (2) We obtained intense radiation around Si-based ultrahigh-temperature heat-resistant materials in high-enthalpy flows by using the spatial-temporal two-wavelength spectroscopic system.
