Abstract

The paper presents the results of measuring the time spectrograms of shock-heated air radiation obtained on the STS-M and DDST-M shock tubes of the Institute of Mechanics (Moscow State University) using an integral method that records the time evolution of radiation passing through the measuring section of the shock tubes in narrow spectral ranges specially selected using monochromators. The measurements were performed for atomic lines and molecular bands in the wavelength range from vacuum ultraviolet to infrared radiation at an initial pressure before the shock wave of 0.25 Torr and shock wave velocities from 7.8 to 11.0 km/s. The obtained results are compared with the experimental data of other authors.
