Analysis of Ultraviolet Radiation Characteristics of Solid Propellant Rocket Motor Exhaust Plume
To study the effect of propellant type and content of aluminum powder on the ultraviolet radiation of solid rocket motor plume, a plume ultraviolet radiation model is build, using two-dimensional flow-field and three-dimensional radiation transfer calculation, taking thermal emitting, CO+O chemiluminescence, OH radical chemiluminescence, Al2O3 particles of different crystalline states and diameters into consideration. The ultraviolet radiation distributions of double base, modified double base and composite propellant rocket motor plume are calculated, and the effect of aluminum powder content on plume ultraviolet radiation is analyzed, taking composite propellant as an example. This study can provide reference for the judgment of missile type in the process of early warning, as well as improvement of missile ultraviolet stealth performance.
