摘    要:对有缝隙的和无缝隙的变尾缘叶栅与变弯度叶栅进行了系统试验研究,取得了这种叶栅的气流转折角和损失以及落后角的变化规律。证实压气机变弯度叶栅可在较小的能量损失下实现较大的气流转折角,其工作特性比可转导叶明显优越。推荐的叶栅构型及其几何参数值可供设计直接使用,它是改善压气机调节性能,防止喘振,扩大稳定工作范围的行之有效的方法。

关 键 词:叶栅 弯度 试验 燃气轮机 压气机

Abstract:This paper presents a systematic and experimental study of variable camber cascades and variable trailing edge ones with and without slots.A variation relationship has been obtained of the flow deflection, flow loss and deviation angles. It is shown that a relatively large flow deflection can result at the cost of a relatively small energy loss by using variable camber compressor cascades and the cascade performance characteristic is markedly superior to that of adjustable guide vanes.The recommended cascade configuration and geometrical data can be readily used for compressor design and may play a significant role in improving its regulation characteristics, preventing compressor surge and securing an enlarged stable operation range.
Keywords:compressor  cascade  experimental study
