| 摘 要： | 对不同内收缩段设计的高超声道流场进行了数值仿真研究,考查了下壁面水平倾角对进气道各性能参数特别是再起动特性的影响.结果表明,减小进气道不起动流场大规模分离区尾部所在下壁面的水平倾角,可以显著提高不起动流场的性能,大幅降低再起动马赫数,但也带来内收缩段长度增加,起动流场性能降低的缺点.为兼顾两者性能,提出了一种新的内收缩...

| Abstract: | The numerical study of hypersonic inlet flow with different inner compression surface was carried out,aimed at exploring the influence of horizontal angle of lower inlet surface on inlet performance specially restarting characteristics.The result shows that the reduction of surface horizontal angle on the tail of separation bubble will improve the performance of unstart flow and decrease the restart Mach number,with the disadvantage of increasing length of inner compression surface and reducing the performa... |
