摘要
在双脉冲发动机地面试车过程中,隔板结构引起了Ⅰ脉冲燃烧室壁面烧穿的问题。利用Fluent流场分析软件,分析了金属膜片式隔板对双脉冲发动机流场特征的影响;通过对计算结果的分析,对比2种隔板结构的优劣,为隔板优化提供参考。
The clapboard structure causes burn-through in I pulse chamber of dual-pulse ground test. The effect of metallic diaphragm in dual-pulse motor flow characteristics is analyzed the Fluent software. According to the numerical calculation, the characteristics of two clapboards lyzed comparatively, which can give reference to the optimization of clapboard. motor m based on are ann-lyzed comparatively, which can give reference to the optimization of clapboard.
