It is no effect on a sidewall compression inlet ' s starting characteristics while a starting sidewall compression inlet is moved cowl to increase interior contraction ratio appropriately . back pressure effect on characteristics of self - starting for hypersonic sidewall compression inlet is tested in mach 3 . 85 wind tunnel . the hypersonic sidewall compression inlet with interior contraction ratio 1 . 24 can self - start . unstart hypersonic sidewall compression inlet caused by high back pressure can self - start by moving cowl to decrease interior contraction ratio
最后,实验研究了反压对侧压式进气道自起动特性的影响,内收缩比1 . 24的侧压式进气道可以实现自起动并且实验验证了由于反压过高而不起动的侧压式进气道,通过移动唇口板以减小内收缩比可以实现侧压式进气道的自起动。
