The article considers the computational and experimental study results of condensed sys-
tem combustor discharge from the double-nozzled gas generator, as well as mixing pro-
cess 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 noz-
zles. The study reveals the regularities of changes in discharged combustion products
flow structure, and the gas-jets interaction processes at different pressures and at differ-
ent diameters of nozzle critical sections in the gas generator.
Keywords: gas generator, energy condensed systems, combustor discharge, mathemati-
cal modeling, experimentation, visualization.
