【Abstract】 The extrapolation problem of the experimental data for low-altitude solid propellant exhaust plume is studied in this paper. The similarity principle is considered to analyze the model of low-altitude solid propellant exhaust plumes, and the similar lows and conditions are presented. A simplified equation which calculates the temperature distributing of low-altitude plume is presented on the basis of semiempirical method and the result shows that the method is available.更多还原
