The article considers the computational and experimental study results of condensed system combustor discharge from the double-nozzled gas generator, as well as mixing process of combustion products. Calculations are based on mathematical modeling of gas-dynamic flow in a three-dimensional way for viscous heat-conducting gas with condensed phase particles. The article analyses gas generator model experimental studies with the charge of energy condensed system of end burning. We used imaging techniques and luminance pyrometry while diagnosing combustor discharge from the gas generator nozzles. The study reveals the regularities of changes in discharged combustion products flow structure, and the gas-jets interaction processes at different pressures and at different diameters of nozzle critical sections in the gas generator.
