摘　　要：文中针对某子母型航弹的实际情况,建立计算模型,采用通用的流场计算软件对不同马赫数条件下进行了数值模拟,得到了不同投弹速度情况下弹底部流场的分布规律,为航弹采用柔性开舱方式选择和子弹出舱过和分析提供了参考依据。The calculation model is established according to actual condition of a cargo aerial bomb in the paper. Through numerical simulation using the general calculation software of flow field in different Mach-number,the regularities of distribution of Rear Flow Field of Cargo Aerial Bomb are obtained about different speeds of bomb-release. The reference bases are provided for flexible opening system selection of aerial bomb and analysis of bullet motion process from cargo.
