Abstract

This paper proposes a model for calculating the characteristics of the radiation of solid-fuel rocket engines (SFREs). The plume of an SFRE is regarded as a gas-dynamic system in which the characteristics of the rocket flight and the distribution profiles of the speed, density, and temperature are linked with the parameters of the gas at the engine’s nozzle section. A basis is provided for the assumptions that have been made to simplify the computational procedure for the plume in its various projections. Calculations of the spatial brightness distributions of the plumes under various conditions showed that the model is adequate when compared with the experimental data.
