Abstract
Addressing the insufficient rapid response in calculating the radiative characteristics of solid rocket motor plumes within high-altitude particle fields, this invention discloses a rapid calculation method for the radiative characteristics of high-altitude particle fields in solid rocket motors. Under the premise of adhering to fundamental physical laws, the plume flow field of the solid rocket motor in the high-altitude region is appropriately simplified to improve computational efficiency. This method reduces the calculation time of the plume particle field to the minute level, providing support for further research on radiation signatures.
