Краткое описание

Spectral emission of the plasma formed in front of a space vehicle entering the upper layer of Mars atmosphere is analysed. The high temperatures behind a hypersonic shock wave leads to dissociation and ionisation of the molecules found in the Martian atmosphere. The chemical reactions responsible for the formation of a Martian plasma are presented. A simulation of the spectra of some of the most important emitting systems is performed (numerical code SESAM), and a comparison with experimental spectra obtained in a low pressure arc-jet wind tunnel is presented. The influence on the shape of the simulated CN violet spectra, of the apparatus function, vibration and rotation temperatures is studied.
