摘要
分析了支线民航机一种新型亚音速带有腔室旁通道的进气道的几何形状设计和气动试验结果。针对某型发展型飞机设计并制造了缩尺比例为１∶２的该型式进气道模型，进行了流态观察，气动性能试验和投掷外来物试验。结果表明，这种带有腔室旁通道的进气道虽然总压恢复系数比某型发展型的带有管状旁通道的进气道稍低，但具有许多优点，尤其是具有很强的排除外来物的能力，对适航性有严格要求的民航飞机来说，这种进气道将有很好的应用前景。
The intake with plenum bypass is a new type subsonic intake for civil medium range aircraft.Its geometry is considered.A model of this type has been designed,which scale is 1∶2.Experiments of flow visualization,gasdynamic performance and foreign object throwing have been done.The experimental results show that its perfect gasdynamic performance and flow steadiness satisfy the requirements of aeroplane and engine.Compared to the intake with pipe by pass,this new type intake has many advantages,especially the improved ability of eliminating the foreign object,although the total pressure coefficient of this type intake slightly lessens.This type intake has extensive application in the future to the civil aviation with the strict requirements of airworthiness.
