Paper Abstract

In order to study the infrared radiation characteristics of the solid rocket plume at high altitude, a numerical method is used to simulate the infrared spectral radiation intensity of a solid rocket plume at three altitudes, which are 120km, 150km and 180km, and the cause of the phenomenon is produced from the flow and radiation transmission views. It is confirmed that the peak value of infrared radiation intensity of the plume is within the range of 4~5 μm, due to the influence of high altitude diffusion effect. At the high altitude, the infrared radiation intensity of the plume increases rapidly at 4.7μm, which is at the CO absorption band. It can be within the same magnitude as the radiation intensity at the 4.3μm, which is at the CO2 absorption band. And the radiation intensity varies slowly with height, there is no severe fluctuation.
