unstart meaning in English
未起动
Examples
- The results show the exit back pressure and length / height ratio of isolator have great impact on exit flow field and starting performance of inlet . high back pressure of inlet will result in unstart
研究表明：隔离段长高比对进气道出口参数影响较大；隔离段出口反压不能太高，否则会引起进气道不起动。 - Scramjet combustor may realize the subsonic - combustion mode and supersonic - combustion mode respectively based on the control of fuel in variable flight conditions . isolator has great effect on mode transition and preventing unstart of inlet . inlet can be unstarted by raising the back pressure result from chemical energy release in the combustor
计算研究表明，在相同的来流条件下，供油规律对燃烧室的工作模态有着重大的影响；在不同的来流条件下，可以通过调节供油规律使燃烧室分别实现亚燃模态和超燃模态；隔离段对防止燃烧引起的压力升高对进气道的干扰和燃烧室的模态转换具有重要的作用。 - 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。
