That is, the sweep is only a degree of freedom for fan/compressor design. It affects compressor’s stall margin by matching aerodynamic loading of all elements along the span over the whole operation range.
本文回顾了“掠”的历史发展,对“掠”机理进行探讨,给出了关于轴流压气机设计中“掠”问题的另类认识: “掠”仅是叶片设计的一个自由度,其通过叶片基元负荷全工况范围内的展向匹配影响轴流压气机失速裕度;通过激波、附面层、叶尖泄漏流、二次流等因素对效率产生影响,这是个折衷过程。
