The study of radiation shock-heated gases provides information on the radiation heat fluxes, which are of great interest for problems in hypersonic aerodynamics. The results of the experimental study of the initial stage of nonequilibrium emission of pure argon obtained at the experimental “Shock tube” complex of the Research Institute of Mechanics, Moscow State University are presented. A simplified model is proposed for the calculation of the radiation intensity of atomic lines behind the shock wave front. The effect of electrons on the features of argon radiation at the initial stage after the passage of the shock wave behind the gas-dynamic front before the beginning of the avalanche ionization is discussed.
