National Olympics Memorial Youth Center), Shibuya-ku, Tokyo, Japan, In our laboratory, the characteristics of radiation behind air shock waves have been studied systematically by using a shock tube. In previous studies, the pressures in high pressure chamber and low pressure chamber conditions were kept as independent variables, and radiation behind reflected air shock wave was observed by a high-sensitivity cooled CCD camera. As a result, the radiation intensities were increased with an increase in the incident shock Mach number. In this study, the shock waves with different incident shock Mach number were produced under the conditions where pressure in the low pressure chamber was kept at constant value and pressure in the high pressure chamber was increased. The radiation behind those reflected shock waves was visualized temporally and spatially by a high-speed video camera. In addition, the time changes of the radiation originated from the chemical species were analyzed by using the high-speed video camera with narrow band-pass filters. The narrow band-pass filters corresponding to atomic nitrogen and oxygen lines were selected, and the filter not corresponding to these lines, namely 520 nm in wavelength, was also done. As a result, the radiation was observed in all the cases with the narrow band-pass filters. However, the radiation intensity obtained from the narrow band-pass filter which does not correspond to these lines is weaker than the radiation intensities obtained from the narrow band-pass filters which correspond to these lines. Thus, there is a possibility that the radiation was due to atomic nitrogen and oxygen lines., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730011025, レポート番号: JAXA-SP-17-004},
