摘要
进气道旋流是进/发相容性的一个重大扰动参数。在发动机稳定性和性能方面进气道旋流的效应也是不可忽视的。讨论了S形进气道/发动机相容性的评定方法,并且建议了有效评定准则。S形进气道/发动机相容性评定必须由两部分组成,一部分与压力畸变有关,而另一部分与流动弯曲度有关。
Inlet Swirl is a major disturbance paramenter in engine/inlet compatibility.Its effects should not be ignored.The procedure for assessment of engine/S-shapedinlet compatibility is discussed, and a criterion for its validity is suggested.The criterionfor engine /S-shaped-inlet compatibility must consist of two parts,one is related withpressure distortion and another with flow angularity.
