波瓣喷管引射器具有高效的引射掺混特性。非轴对称波瓣喷管引射器的引射特性与轴对称波瓣喷管引射器有所不同。本文对六波瓣的非轴对称喷管引射器进行了一系列的实验，研究了该引射器的引射流量比与主流温度的关系，混合管动量修正系数及其工作特性曲线。最后通过分析得出了与实验数据基本符合的理论工作特性关系式 Lobe nozzle ejectors have efficient ejector blending characteristics. The non-axisymmetric lobe nozzle ejector has a different ejection characteristic than the axisymmetric lobe nozzle ejector. In this paper, a series of experiments on a six-lobed non-axisymmetric nozzle ejector were carried out. The relationship between the ejector flow ratio and the mainstream temperature, the correction factor of the mixing tube and its operating characteristic curve were studied. Finally, we get the relationship between theoretical work characteristics and experimental data
