摘　　要：某型燃气-蒸汽式导弹发射动力系统工作机理复杂,在工程研制中需要开展大量的缩比试验,亟需研究与该技术相匹配的缩比相似理论。文中通过对该物理和数学模型的分析,提出了缩比模型的相似约束条件,建立了发射筒和导弹上下不同截面的缩比试验方法,解决了缩比与相似约束条件之间的矛盾,可为该型发射动力系统和其他水下缩比试验研究提供参考。The work mechanism of one gas-steam type missile launching power system is complicated, so a mass of sealing-down tests are required to be accomplished in the engineering development of the launching power system. Therefore, the sealing-down similarity theory matched with this technology was desiderated to be researched. Through analyzing the physical model and mathe- matical model, the similarity constraint condition of the scaling-down model was provided, the scaling-down test methods of launch tube and different sections of upper and lower part of missile were established, he conflict between scaling-down and similarity constraint condition was solved, and this paper can provide reference for this launching power system and other underwater scalingdown test research.
