Istraživana je katalitička aktivnost balističkih modifikatora: baznog olovo-stearata, kalcijum-karbonata, kobalt (IH)-oksida i čadi, za različite masene udele azota u nitrocelulozi, kao komponenti dvobaznog raketnog goriva, kao i uticaj veličine čestica balističkih modifikatora na brzinu sagorevanja dvobaznih raketnih goriva. Kao mera katalitičke aktivnosti korišćen je koeficijent katalitičke aktivnosti, koji predstavlja odnos brzine sagorevanja referentnog modela dvobaznog raketnog goriva sa modifikatorima i brzine sagorevanja referentnog modela dvobaznog raketnog goriva bez balističkih modifikatora. Prikazani su eksperimentalni rezultati ispitivanja brzina sagorevanja dvobaznog raketnog goriva. Izvedeni su odgovarajući modeli zavisnosti brzina sagorevanja odpritiska u raketnom motoru. / The investigation described in this paper concerns the experimental phenomenological study of catalytic activity of ballistic catalysts: basic lead-stearate, calcium carbonate, cobalt trioxide and carbon black for different mass portions of nitrogen in nitrocellulose as components of a double base propellant, as well as the influence of the dimensions of ballistic catalyst particles on the double base propellants burning rate. The catalyst activity ratio in used as a measure of catalyst activity, and it represents the ratio of the burning rate of a double base propellant with catalysts referent model to the burning rate of a double base propellant without ballistic catalysts referent model. The paper gives the experimental results of the double base propellant burning rate. The appropriate models of the burning rate dependence on the pressure within the rocket motor are derived
