Beschreibungen/Notizen

• The results of measuring the integral and temporal spectral characteristics of shock-heated air are presented. The experiments are carried out on a modified two-sections SST-M shock tube of the Institute of Mechanics, Moscow State University in shock wave velocities ranging from 7.8 to 10.7 km/s and initial pressures in the low-pressure chamber of 0.125 and 0.25 Torr. The radiation wavelength range 115–195 nm, corresponding to the vacuum ultraviolet (VUV) spectral region, in which the main contribution to the radiation is made by the atomic lines of nitrogen and oxygen, is studied. The obtained radiation spectrograms are analyzed. The measurement data are compared with the available experimental data of other authors.
