导弹水下垂直发射过程数值仿真分析

摘要

潜载导弹发射时处于深水环境，导弹运动过程中所承受的载荷及发射装置承受的载荷等都与陆基发射有很大差别。利用Fluent动网格技术结合多相流模型对发射时导弹筒内运动过程的非定常流场进行仿真，重点分析不同发射水深、不同内外筒排导间隙情况下导弹出筒速度以及弹体、发射筒受力等。%The submarine missile is launched in the deep water. The loads of submarine missile and launcher are very different with that of land launch. The unsteady flow filed of moving process during launching was simulated by using Fluent dynamic mesh combined with multiphase fluid and different clearance of interior and exterior launch tube.
