A method and equipment for optical diagnostics of liquid-fuel 
rocket engines (LR) is described. Experimental data on minimum detectable 
concentrations of such metals as Fe, Al, Mn, and Ni in the plume have 
been obtained. The radiation spectra of the plume of the engines of 
stages II and III of the Proton carrier rocket (CR) and of the full-scale 
oxygen-kerosene LR have been measured.
