摘要 本文针对固体火箭发动机低空羽流场的数据外推问题进行研究。应用相似方法分析发动机低空羽流场模型,整理相似准则及相似条件。简化相似模型,根据工程计算半经验方法,拟和低空羽流温度场的计算公式,计算结果与工程计算数据基本吻合,验证了相似方法的可行性。 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.
