N this paper the effect of ultra fine carbon particles (soot) on combustion rate of high calorific model ballistic propellant, based on nitroglycerine, is studied. More than 0,3% soot content decreases combustion rate of basic propellant. The temperature distribution in combustion wave of the above propellant with and without a small amount of soot is also compared to determine the effect of radiation from high-temperature flame zone on the condensed zone just below the combustion surface. The results confirmed that the degree of blackness does not affect on preheating of condensed phase by radiation from high-temperature flame zone. This is probably due to the fact that soot particles are formed as intermediate products on the combustion surface of transparent sample, which in turn absorb the radiation.
