Paper Abstract

The analytical models were adopted to rapidly find out and simulate rocket plume apparent infrared radiation intensity observed by satellite in the wave bands of 2.7 um and 4.3 um at various altitudes at boosting stage. Specifically, a rocket plume flow field was first of all divided into three regions-highly under-expanded initial region, free turbulent efflux transitional region and free turbulent efflux main region-to build up a simplified flow field model of rocket plume. Then by simplifying the atmospheric emission and absorption factors into vapor and carbon dioxide only, we divided the heterogeneous plume into several homogeneous layers along the observation direction, which enabled us to construct a layered infrared radiation integration model of rocket plume. After that, we formulated a spectral transmittance model of each layer of plume by use of the Curtis-Godson approximation HITEMP database. The final step was the modeling of atmospheric spectral transmittance by means of the Combined Atmospheric Radiative Transfer (CART) software. Simulated curve for the intensity of rocket plume infrared radiation bears high similarity to the one measured by satellite.
