摘　　要：为完善非定常多体分离风洞试验技术,增进相关领域的研究人员对该类试验技术的了解,对两种研究飞行器多体分离问题的非定常风洞试验技术——多体分离风洞自由飞试验技术和风洞投放模型试验技术,技术特点、相似准则及应用领域等方面的共性特点和差异作了总结和分析。比较了两种试验技术相似准则问题中的轻、重模型两种方法的优缺点,给出了两种非定常多体分离风洞试验技术在级间分离、子母弹抛撒分离和导弹蒙皮/壳片抛撒分离、重块抛撒分离和整流罩分离、飞机外挂物投放分离和内埋武器投放分离等各类多体分离问题的适用性对比分析。To improve the unsteady wind tunnel test technique on multi-bodies separation,and make the relevant researcher further understand the technique,the characteristics,similarity criteria,and application field are summarized for two unsteady wind tunnel test techniques on multi-bodies separation,which are multi-bodies separation wind tunnel free-flight test and wind tunnel drop-model test techniques. The difference between two techniques is analyzed. Comparison is made between heavy scaling and light scaling,for both wind tunnel drop-model test and multi-bodies separation wind tunnel free-flight test technique. The applicability is analyzed for the two unsteady multi-bodies separation wind tunnel free-flight test techniques,on various multi-bodies separation,such as stage separation,submunition disperse,cover separation,weights disperse,shroud separation,jettisons of airborne external stores and internal missile separation.
