Influence of various (0,1-5 %) quantities of finely dispersed soot KGO-250 on combustion regularities of high-energetic propellant (Q zhe = 5619 kJ/kg) is investigated. It is shown, that depending on the content amount and pressure at which combustion takes place, soot can either increase (up to 10-20 % at 0,1-1,5 % of soot content) combustion rate, or reduce it (by ~20 % at 5 % of soot content). It is established, that 1,5 and 5 % of soot render significant and complex influence on temperature distribution in gaseous zone, probably, for the account of catalyzing exothermic reactions with participation of NO and for the account of endothermic interactions with CO 2 and H 2O. It is shown, that a sooty layer is formed just above the condensed- phase reaction layer of propellant, the upper boundary temperature of which is about 50-80 K higher than the temperature of condensed- phase reaction layer.
